19523	Host audio not working after launching the guest	VirtualBox 6.1.6	defect	2020-04-22T21:58:57Z	2021-10-15T08:51:59Z	2021-10-15T08:51:59Z	"I have an issue where the host audio disappears/doesn't work after the guest is launched.

I have tried disabling the guest audio (VM setting no audio), and full audio from the VM settings, but this makes no difference. During the boot, the audio for the host disappears. I've booted with the guest extensions installed and uninstalled, both exhibit the same outcome. Host is macOS Catalina (10.15.4), Touch Bar 2018 MacBook Pro.

After the VM is shutdown, the host audio will return, but it has a slight echo at the end of any audio play, just as the audio ends it stutters.

It was first noticed by me in 6.1.2, but may have been earlier and persists in 6.1.6 and 6.0.20.
Hardware diagnostics return no errors on the host.

I have reduced the RAM allocated, from 4G (50%) to 3G and the audio seems to be ok. From a thread in the forums (https://forums.virtualbox.org/viewtopic.php?f=8&t=96902), a new guest (VDI) built from scratch seems to be ok.

I copied the VM over to a non-touch bar MacBook Pro (late 2016) and it appears to run without breaking the host audio (logs also attached).

It will most of the time. It even happens when a user logs in and the startup sound keeps playing until you play another audio file and stop it multiple times until all noise stops. 	RexBuyeo

For the guest OS I have tested several Linux guests, I have not tested non-linux guests.

Steps to reproduce this bug:

1. Create a new VM using an Ubuntu host and a Linux guest. (I don't know if this bug effects other hosts)
2. Open the settings for the VM, click the audio tab and uncheck the ""Enable Audio Input"" setting.
3. Start the VM.
4. Use some application inside the VM to record audio or just look at the microphones sound levels from the guest OS's audio input settings."	eqkb
19395	Solaris guest appears to hang for minutes after keyboard bell	VirtualBox 6.1.4	defect	2020-03-12T08:09:50Z	2021-03-30T22:56:38Z	2021-03-30T22:56:38Z	"There is an apparent misbehavior I noticed when running Solaris 11.4 and Solaris Trunk guest VMs, it appears to hang/freeze for a couple of minutes when you get the Gnome terminal to issue a keyboard bell, eg. when you delete more characters in the command line using the backspace key as there are. Then the keyboard bell rings and then the guests Gnome desktop appaers to
be frozen for a couple of minutes and then returns back to normal.
This is very simple and quick to reproduce.

It sounds like some problem with audio, but I don't know if anyone runs Solaris on real hardware that has audio and can verify if that
happens as well on bare metal using Gnome.

This happen regardless whether or not one uses the Gnome terminal or just a simple Xterm. Same result.

That might be a bug in our audio emulation or in Solaris.

And when it is hung serial console access works fine so it is just Gnome that is stuck/frozen for a couple of minutes.

The problem does not show up with Solaris 10 or OpenIndiana based guest VMs running their corresponding Gnome desktops."	Frank Batschulat (Oracle)

21100	Microphone is too silent in the VM with Windows 10 or 11	VirtualBox 6.1.38	defect	2022-09-08T23:10:29Z	2022-09-08T23:10:29Z	2022-09-08T23:10:29Z	"I have an old problem with microphone: even with the maximum level on the host, it is nearly silent in the guest. If I test it on the host, I can see the level goes to 100%, but the same test in the guest gives only 10% volume.

I searched the tickets and forum. All I could find is the suggestion to use Line-in in pre-Windows 10 versions, but there is no Line-in in my Windows 10 or Windows 11 VM. My host is Windows 10 by the way.

So, my question is: are there any other possibilities to bring the microphone volume to the right level in the guest?"	boxer01

Starting with virtualbox 6.1.28 (tested as well on 6.1.30, 32, 34 so far) there is no audio input after rebooting a Windows 10 guest VM. The audio interface is present, but only silence as audio ""in"" after a reboot (audio was present at first boot). Everything was working well with virtualbox 6.1.26 or before.

The problem is easily reproduced at first try on any machine I have (tested several hardware, different sound cards, different CPU architecture amd or intel, different host os : debian 11 or windows). The problem always apear after the first (and any subsequent) reboot of the machine (either user induced, or due to and update or a VM crash).  

Also tested several Windows 10 versions (LTSC ; entreprise ; home), all have the same problem.
Depending on the host, I have tested several drivers (Alsa and PulseAudio on Linux and ""Windows Direct Sound"" on Windows).
The problem is the same if the Guest Additions are installed or Not (therefore, not a problem with the GA).

Please see attached some logs taken with extended audio logs using options ""VBOX_RELEASE_LOG=drv_host_audio.e.l.l2.l3.f+drv_audio.e.l.l2.l3.f+audio_mixer.e.l.l2.l3.f+dev_hda_codec.e.l.l2.l3.f+dev_hda.e.l.l2.l3.f+dev_ac97.e.l.l2.l3.f"" :

I've got no in&out audio anymore since upgrading my vm to release Pop!OS 22.04. Maybe because the audio subsystem is now using Pipewire ? 

More precisely, for Windows DirectSound + Intel HD Audio. Only ICH AC97 does produce sound. But it's heavily garbled. 

Since this is an Ubuntu based distribution I presume this happens to all Ubuntu 22.04 releases. 

Rebuilding the kernel with the guest additions didn't help.

Is there anything I can try or help with to resolve this issue ?"	JLC

20786	Strange audio related VM lockups	VirtualBox 6.1.32	defect	2022-01-21T03:29:23Z	2022-04-28T20:50:24Z	2022-04-28T20:50:24Z	"I am experiencing lockups related to audio playback in VirtualBox. To clarify, lockup means that Virtualbox locks up, not the guest; pressing the reset button in virtualbox does nothing. The window will not close unless I issue a ""killall VirtualBoxVM"", but the UI remains mostly responsive. This has been happening since around 6.1.24. 6.1.22 is the latest version that works fine. On the host, I am using ALSA without pulseaudio. I normally use a very customized asoundrc file, but even without my special ALSA configs, the issue still occurs. 

On a WinXP guest, I am experiencing a complete freeze when attempting to move the volume slider and sometimes audio playback causes a freeze. 

On a Ubuntu 16.04 guest (kernel 4.4), audio playback happens too fast/slow sporadically. When this happens, I see lines like these in dmesg on the guest.
[    9.025442] snd_intel8x0 0000:00:05.0: intel8x0_measure_ac97_clock: measured 55894 usecs (2880 samples)
[    9.025446] snd_intel8x0 0000:00:05.0: clocking to 44715
When that value (44715) is below 48k, audio is slow. When above, it's fast. Rebooting the VM seems to randomly change this ""clocking to ..."" value. Also, occasionally, after a long audio playback session with google chrome + youtube the VirtualBox instance will hang on shutdown (VM guest shuts down, but window remains open)."	li200

20723	Guest can't pick-up/use Host audio device (like BT or USB headset) after the device was physically reconnected/re-plugged (LOGS, STEPS)	VirtualBox 6.1.30	defect	2021-12-13T01:16:59Z	2021-12-13T01:16:59Z	2021-12-13T01:16:59Z	"Pls advise on temporary workaround (if any), as it blocks from using some of audio devices with VirtualBox (greate solution, btw, thank you so much!)

Steps:
1 Choose some pluggable audio device on Host. It can be any - USB or Bluetooth/BT headset/headphones, behavior is the same
2 Play audio in Guest
3 Disconnect/unplug audio device physically from Host
4 Audio playback falls back properly to the newly selected Host audio device (like speakers of a laptop)
5 Plug-in/reconnect disconnected USB or BT audio device, ensure it's selected as default in Host and audio plays just fine from Host
6 Try to play audio from Guest
RESULT: silence, nothing audible
I've expected audio to play normally, but it can be done only if I restart Guest

What's interesting is that if after step 6 I switch Host's audio device to 
the fallback device (like laptop's speakers), I start to hear Guest's audio. So the audio itself is not broken in Guest.

What I've tried to do to get it back:
* Disable/enable Audio Out/In in VB's toolbar
* Mute/unmute, ensure that all is unmuted after reconnections
* Stop/Start audiosrv and AudioEndpointBuilder on both Host and Guest
    The only uncertain thing here is that after some sequence of Stop/Starts I think audio started to go out to proper device, but then I couldn't reproduce/restore exact sequence of starts/stops so I'm no longer shure it wasn't a misinterpretation.

Pls note that if to change audio device back and forth without disconnecting/unplugging it, all works fine as expected.
Just in case, speaking of BT device - it's connected to the Host's bluetooth not to the Guest bypassing Host (if to pass-through BT device ""Intel Corp. [0002]"" to Guest)

Please help to solve it and if possible, suggest temporary workaround for the issue (through CLI), so I can restore audio without a need to restart Guest.

I've attached two set of verbose logs, ""Audio issue - NOT OK unplugging"" represents the issue. ""Audio issue - OK changing without unplugging"" is for the simple change without unplugging (just in case).

20729	High definition audio: cannot control volume with standard pin widgets	VirtualBox 6.1.28	defect	2021-12-15T02:09:15Z	2021-12-15T02:09:15Z	2021-12-15T02:09:15Z	I was writing a driver for High definition audio controller, I found that standard HD audio pin widgets cannot control the volume/mute of Sigmatel codec for output. Even direct output widgets cannot control the volume/mute of output converter. To control the volume/mute we need to communicate with the stac codec directly through controller interface. This need fixes as the standard method described by intel, should work. 	Manas Kamal
20630	Sound disappears after second change from Speaker to Bluetooth Headphones on the host	VirtualBox 6.1.28	defect	2021-10-24T12:04:54Z	2021-12-13T01:22:32Z	2021-12-13T01:22:32Z	"This is a duplicate of the ticket #20431. The description and the analysis of the issue is already there. The error is here since 4 versions (was caused by the another refactor of sound backend back in the March 2021). It still here in the version 6.1.28 147628 and 6.1.29 147791, so I opened this duplicate.

Quick description here: after the host output device changes from Speaker to Bluetooth, then back to Speaker and then once again to BT, the sound output from VBox is lost. Other application from the host still can use the BT as output, but VBox can only use the Speaker after that. The only remedy is to restart or to save and restore the VM, but this only gives one single more short for the BT. After that the whole situation repeats itself.

Steps to reproduce:
1. Download fedora 34 workstation from:

3. Run the virtual machine.
4. When it finishes loading into live-cd, press alt+f2. Then type ""orca"" without quoates and press enter.
Expected result:
The audio driver should work and you should hear: ""Screen reader on"". Then you can continue with the installation or exploring live-cd with orca enabled.
Actual result:
After typing ""orca"" in run dialog and pressing enter, there is no sound in live-cd.

Audio driver closes when using the console linux screen reader in guest	VirtualBox 6.1.26	defect	2021-10-12T18:34:12Z	2021-10-12T18:34:12Z	2021-10-12T18:34:12Z	"When using a linux console screen reader ""espeakup"", audio driver in virtual machine can close at any time while this screen reader works.
As a result, a totally blind person can leave without speech during using the console mode in linux.
As the great example to demonstrate the issue can be installation of the textbased linux distros such as debian, arch and others.
Steps to reproduce:
1. Download the debian iso.
2. Create the new debian virtual machine.
3. After running the machine, enable the accessibility installation by pressing ""s"" then ""enter"" key. You will hear as espeakup says: ""select a language"".
More information on debian accessibility installation process is listed here:
https://wiki.debian.org/accessibility#Debian_installer_accessibility
4. Move between the listed variants with keys numpad 7 and numpad 9, these are espeakup's screen reader keys.
5. Try to continue the installation by following provided instructions.
Expected result:
The audio driver should not close while the espeakup console screen reader works.
Actual result:
Audio driver can close at absolutely any time. You can not predict this action. As the result, a totally blind user is not able to install the linux text based guest operating system to a virtual machine and he should restart the machine and start the whole process over.

Fedora 34 makes Pipewire as default, while it has a pulseaudio module to maintain compatibility, VirtualBox can't play sound with Pipewire, and it affects video playback as well.

Under GNOME settings, there is a testing option under sound preferences, no sound is available in the test.

If there is a video in a web page, like YouTube, sometimes sound can play 2-3 seconds but then the video will be muted, and frames are freezed as well, not only sound is unavailable but the video is affcted as well.

I tried to remove Pipewire and install Pulseaudio, everything is ok and back to normal again.

As Pipewire introduces many new features and better integration in future Linux development, it would be important to fix this issue before pulseaudio is completely phased out (it may take 2-3 years though...)."	Promet

The driver continues working with real hardware and QEMU. After debugging and analysing VBox code I think a regression was introduced in rev 76862 by deleting the ichac97R3StreamFetchBDLE(pThis, pStream); call when setting up LVI register.

What happens now is that CIV register is advanced, but the PICB register is not refreshed (refresh is done ichac97R3StreamFetchBDLE(pThis, pStream)). What then happens is when ichac97R3StreamTransfer() is called, the cbLeft is zero so the whole logic of this function is skipped. The ""hardware"" hangs in mode where DMA is saying its active, Bus Master is enabled but nothing is tranfered. The only way to kick the ""hardware"" again is to set the CR register where the code again advanced the CIV but then calls ichac97R3StreamFetchBDLE() to update PICB. This way however a previous buffer is lost.

There are two places I see possible to change:
- restore the call to ichac97R3StreamFetchBDLE when setting LVI and advancing CIV
- allow ichac97R3StreamTransfer to operate with *initial* empty PICB just like the code in the look (when it sees empty PICB it continues to next buffer)"	deadwood

Background is here: https://forums.virtualbox.org/viewtopic.php?f=6&t=98365 but I'll put everything important in this ticket.

The bug only occurs on Windows hosts (W10 1909 tested) - Linux hosts are fine.

No amount of disabling/re-enabling Audio in the Manager will return the VM to a working state, but suspending the guest via its own mechanism and then resuming it generally effects recovery, so my (ignorant) gut feel is that something has changed in the timing or behavior VBox's handling of suspend/resume that's caused the audio pieces to not quite sync up (i.e. resumed before ready or etc).

I have some potentially-useful endpoints to reduce the bisection, in the 6.0 branch: LKG is 6.0.12, FKB is 6.0.22. (The bug is also in the 6.1 branch since at least 6.1.6, through to 6.1.10, but I don't have any working versions of 6.1 to provide the other end).

VirtualBox 6.0.8	defect	2019-06-07T06:36:04Z	2022-12-06T02:39:19Z	2022-12-06T02:39:19Z	"This is a new issue caused by some changes in November 2018. Those changes were done because of the issues in ticket #17225. Because the issues of the other ticket are solved and this is just follow-up issues caused by the changes in the other ticket, I open this one just for those issues.

The issue was already described in the old ticket, I also put some logs there, so I kinda link there for further information and logs (see comment 74 and some previous ones in #17225 for example). Some brief description: as soon as one changes the audio output device on the host (speakers to head phone or Bluetooth; or in the other direction), the guest’s audio output is simply stuck forever in the last second on the old device. The solution is always tricky, I described some of the working ones in the comments of ticket #17225. Sometimes only help is the guest’s reboot."	boxer01

Reproduced on the following host OS:
- Windows 10 latest update
- Debian 9 ""Stretch""

Tested guest OS:
- Debian 8
- Debian 9

I'm a blind person so I rely only on sound so me and other people using sound (included many other blind people) I know has confirmed this issue to me.

Steps to reproduce:
1) Download the Debian 8 iso here:https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/archive/8.11.0+nonfree/amd64/iso-cd/firmware-8.11.0-amd64-netinst.iso
2) Create de Debian 64 bits virtual machine
3) Configure the sound control on Intel and check if enable audio output is checked
4) Boot on the Debian installer
5) On the first screen choose install with speech (press s and enter with keyboard)

Result:
No speech

Expected result: 
speech

7) Disable and then enable audio output on the fly

Result:
Speech

Note: The issue also exists on installed OS but I've give the easiest way to reproduce it
Note2: The issue doesn't appear on Virtualbox 5.2
Note3: The issue doesn't appear on a physical machine

18544	detection and configuration of pulse audio is inconsistent	VirtualBox 6.0.4	defect	2019-04-04T19:46:53Z	2019-04-05T09:05:02Z	2019-04-05T09:05:02Z	"
The way 'configure' detects and enables Pulse audio support is inconsistent and seems like there may be some steps missing.

- unlike most of the check_<something>() functions in configure, if check_pulse() is even
  called (more on that in a minute), and it detects that Pulse is present and usable, it
  doesn't do anything to enable Pulse.  In particular it does not call

    cnf_append ""VBOX_WITH_AUDIO_PULSE"" ""1""

  if it finds pulse.

- in addition to the fact that check_pulse doesn't set the define, check_pulse is limited to
  only being called on certain platforms, by this code:

{{{
  if [ ""$OS"" = ""linux"" -o ""$OS"" = ""freebsd"" -o ""$OS"" = ""netbsd"" ]; then
    if [ $WITH_PULSE -eq 1 ]; then
      check_pulse
    elif [ $WITH_PULSE -eq 0 ]; then
      cnf_append ""VBOX_WITH_AUDIO_PULSE"" """"
    fi
 fi
}}}

- finally, if you pass --enable-pulse to configure, it sets WITH_PULSE=2 ... which does
  nothing.


What I think should happen, to make this more consistent:

1) check_pulse() should be modified so that

    - if it finds working/acceptable pulse, it calls cnf_append to
      add VBOX_WITH_AUDIO_PULSE=1
    - conversely, if check_pulse is called and it *doesn't* find acceptable pulse,
      it should call cnf_append to set ""VBOX_WITH_AUDIO_PULSE"" """"

2) the code block that decides whether check_pulse should even be called should be adjusted so that it doesn't restrict the call by OS and it handles the --enable-pulse case.  Some preliminary code might look like:


{{{
  if [ $WITH_PULSE -eq 1 ]; then
    check_pulse
  elif [ $WITH_PULSE -eq 0 ]; then
    # --disable-pulse or platform default
    cnf_append ""VBOX_WITH_AUDIO_PULSE"" """"
  elif [ $WITH_PULSE -eq 2 ]; then
    # --enable-pulse was passed
    cnf_append ""VBOX_WITH_AUDIO_PULSE"" ""1""
  fi

}}}

These changes still honor platform defaults for darwin & haiku (both set WITH_PULSE=0 early
in configure).  If there isn't a platform-specific override, then the configure default of
WITH_PULSE=1 causes check_pulse() to be called, and it sets VBOX_WITH_AUDIO_PULSE appropriately, based on whether it found pulse or not.  Finally, if --enable-pulse is passed
to configure, VBOX_WITH_AUDIO_PULSE=1 is forced on, with no call to check_pulse.

I can provide patches to configure to make these changes, if you agree that the proposed changes are good ones and make things more consistent.

After upgrading I noticed that the screen reader gets muted for a while and starts speaking again. The problem happens suddenly and frequently. When it gets muted and I switch to the host window and go back to the guest, it starts speaking again and after some seconds (or minutes) the problem repeats.

I've already confirmed that the problem isn't related to the screen reader; its commands continue working even when it is muted and there are no logs showing a NVDA crash. Initially, I thought that the entire audio was being affected by the problem, but when I play a video (from Youtube, for example) in background and continue to use the screen reader, surprisingly the issue doesn't happen (after stopping the video the problem back to arise as before).

Most use in DOS hinges on making use of an I/O address such as A220. That is what I'm hoping you can implement along with the address for MIDI support (i.e. P330). I do not know how you implement the interrupt and high/low DMA but seems like the I/O address has been the biggest issue stopping sound from working.

Also, how exactly is your sound virtualization implemented?  Is there a module that can be added to VirtualBox to accomplish this (something like an Extension Pack for DOS), or is there a module that can be added as a 'pre-boot' BIOS extension inside the DOS guest (similar to how OnTrack DDO used to work)?"

17518	Scratchy/cracklinkg sound on all VM with Windows host	VirtualBox 5.2.6	defect	2018-02-01T19:37:48Z	2018-02-02T18:52:43Z	2018-02-02T18:52:43Z	"For quite a long time (at least 5.1.26, but probably earlier, i think i got this problem back in 5.0.6 on winxp, but I'm not sure) there's a problem with scratchy sound on all my VM. It doesn't matter it's windows xp, 8.1, 10 or various linuxes (ubuntu 14.04, 16.04, 17.10, manjaro) sound is scratchy, but new windows (8.1, 10) are worse. I tested it on 3 machines, one with win7 and two with win8.1. It doesn't matter it's new vm, old one, with or without addons.
The best part is, everything is ok on linux hosts (same vm, same pc).

How is sound scratchy? When playing any sound (win8.1 test sounds in device settings are best example) are similar to electronic crackling 50% of time. When playing music it gets a little better, but still ~10% of time it's crackling.

00:00:02.768338 Audio: Initializing DirectSound audio driver

00:00:02.797189 Console: VM runtime error: fatal=false, errorID=HostAudioNotResponding message=""Host audio backend initialization has failed. Selecting the NULL audio backend with the consequence that no sound is audible""

In DrvHostDSound.cpp, line 2253 the intialisation happens on a fixed audio device interface ID (of what I can see, I am not 100% sure, just looks like it). Rather build an ""enum"" list of sound devices in the computer. These audio devices can have any IDs. Make that list available in the user interface by audio device name (two lists for Sound In and Sound Out). The user can then select the audio device he/she wants to use, one for sound in, and the other for sound out. So then it does not have to be the default audio device. The user can have several audio devices, e.g. Intel HD Audio, Creative audio, NVidia Sound, etc on the Windows host.

The default audio device fails on my machine, since I have a Creative Audio Product, which has a non-standard GUID.

Attached I have the user interface of the audio tab (there is no device selectable, only a default WindowsDirectSound Device. That's no good. Make a list of direct sound audio devices available in the computer, and expose that list to the user interface. That way, the user can select the audio device to use (does not have to be default, then).

The issue is here, /src/VBox/Devices/Audio/DrvHostDSound.cpp, line 2253:

static DECLCALLBACK(int) drvHostDSoundInit(PPDMIHOSTAUDIO pInterface)
{
    PDRVHOSTDSOUND pThis = PDMIHOSTAUDIO_2_DRVHOSTDSOUND(pInterface);
    LogFlowFuncEnter();

    int rc;

    /* Verify that IDirectSound is available. */
    LPDIRECTSOUND pDirectSound = NULL;
    HRESULT hr = CoCreateInstance(CLSID_DirectSound, NULL, CLSCTX_ALL, IID_IDirectSound, (void **)&pDirectSound);
    if (SUCCEEDED(hr))
    {
        IDirectSound_Release(pDirectSound);

        rc = VINF_SUCCESS;

        dsoundUpdateStatusInternal(pThis);
    }
    else
    {
        DSLOGREL((""DSound: DirectSound not available: %Rhrc\n"", hr));
        rc = VERR_NOT_SUPPORTED;
    }

The IID_IDirectSound should be an enum list with all audio devices attached to the host computer, make that list available in the user interface, so the user can select an audio device of his choice by device name.

It would be nice to also get that feature on the Virtual Box 5.2 for 32-bit Windows hosts, which I am currently using.

https://forums.virtualbox.org/viewtopic.php?f=7&t=93940

For the following weeks I tried playing with various configurations including .asoundrc and asoundrc.conf, the VB audio settings and tools like alsamixer and not a peep. It was extremely frustrating

Sound worked just fine on a quick boot up in qemu. I was about to give up on VB when someone with the identical problem replied to the above thread reporting that reverting to 5.2.18 corrected it. Doing so corrected the issue for me also.

There are logs attached to the above-mentioned thread.  I was also emailing various logs and command output to someone for assistance so may have something else useful in history.

Here are my system specs:

Host: Devuan Jessie 32 bit

Guests: Devuan ascii and Devuan Beowulf also 32 bit, of course.

I was using these VMs for package testing and had not previously tested audio.

Thanks you and hope that you can find the bug and correct it.

I use Windows XP for using Microsoft Encarta Encyclopedia 99. It may be a bit outdated, but just because something is a bit outdated does not necessarily mean it has lost its charm. The problem I have with Windows XP is that the sound truncates just before the sound clip ends. For example, when I hear the sound clip that is supposed to go ""That's one small step for man. One giant leap for mankind."", it actually goes ""That's one small step for man. One giant leap for--"" and all the other sound clip ends just like that and it is very annoying.

Starting with virtualbox 5.2.20, the audio began to not work properly for me.  When I try to play some audio, I hear the first part of the audio, but it is cut of a short time before the end. So, if I for example try to play a file containing the words ""Hello World!"", I may only hear ""Hello Wo"". If I then try to replay the file, it works exactly as previously: I only hear the first part of the file. It works with virtualbox 5.2.18, but not with 5.2.20 or later, so the bug was introduced with the 5.2.20 release.

I am running windows 7 as host and headless arch linux as guest. I am using alsa as sound server on the guest.

I will attach VBox.log and a webm file where I try to play audio. The webm file is recorded video from the guest. I try to create a file containing ""Hello world!"", called hello.wav, with espeak.

It should be the first case in Diagnosis table

Same issue with a previous configuration Host: Windows 7 Guest: Ubuntu 16.04 with many versions of VirtualBox.
Only VirtualBox 5.2.7 solved partially as instead of distorted sound it goes mute. 

Thanks.[[BR]]

P.S. Classified as major priority as this issue is a long time pending.[[BR]]

P.P.S. by the way debug wav files are not compatible with windows media player"	Han Fastolfe

The situation has changed after some experiments in the audio back end. So now this distortion is always slightly here and can be clearly heard. But not in the dumped files. Previously this distortion came for thirty seconds every 5 or 7 minutes, but then the sound was heavily distorted. Hope this would help to locate and eliminate this issue.	boxer01

In Virtualbox 5.0.26 (up to 5.0.40 in my pc) it worked perfectly. After 5.1 the issue began.

I already tried setting all the audio combinations in Virtualbox (alsa and pulse with all available audio controllers) but the issue remains.

I have done this procedure https://www.virtualbox.org/wiki/AudioDebug and will be attaching a zip file containing the VBox.log file and 3 wav files."	pemartins

If I use the HD Audio driver for the guest, the audio lags behind the video a few frames for any streaming video such as news or YouTube.  Also, there is distortion, popping, crackling, skipping, etc. of the audio.  After switching to AC97 ICH in the guest, the LAGGING problem goes away.  However, the distortion persists.

I followed the steps for Audio Debugging in the Wiki.  The WAV file also exhibits some distortion when played on the host, though perhaps not quite as noticeable as the distortion in the guest.  I am attaching the VBox.log file.

Finally, it may be worth noting that NONE of these issues existed for me when I was using VBox version 5.0.26.  Every version of 5.1 I have tried as well as the newest 5.2 has this problem."	LittleJeff1970
17321	Unhandled exception in DirectSound	VirtualBox 5.2.0	defect	2017-11-28T14:04:43Z	2018-03-18T04:47:20Z	2018-03-18T04:47:20Z	"Vbox crashes when resume a vm on my win 10 host. It happens 90% of time to vm which has audio enabled.

There is a problem with my windows 10. The DirectSound device has a problem(0x88890008, I don't think the meaning of the code is ERROR_NOT_ENOUGH_MEMORY). The error causes any application which uses DirectSound no sound on my win host. The other applications(such as media player, audio player) simply have no sound output. It should not cause the crash though.

A suggestion from me is to check this exception and ignore it(or report to user whichever solution applies to your coding standard). No crash is expected. I knows the issue with DirectSound so I do expect some of applications do not output sound. It is good to have an option to select device from DirectSound or WASAPI. Audio output available when switch to WASAPI in some applications. It's very strange.

If you need more info, I'll attach log files.

I use heavily GuitarPro 4 and when I press Play, the program start playing as the cursor moves around the notes, but the sound lags behind and the playback  starts approximately 2 seconds after the pressing. When I want to stop playing, the moving cursor, which shows which note is being played at the moment, stops immediately but the sound actually stops after 2 seconds. 

This lag is presented everywhere - for example start a browser and watch video on YouTube - sound and picture walk past each other and the synchronization is lost.

17273	5.1.24 regression: Windows 10 guest microphone stops working after high host CPU load	VirtualBox 5.1.24	defect	2017-11-14T16:39:12Z	2018-03-21T07:02:43Z	2018-03-21T07:02:43Z	"In VirtualBox 5.1.24, when the host CPU usage gets very high (i.e., close to 100% on all cores), then the microphone in a Windows 10 guest stops receiving sound. Note that it continues to receive no sound even after the high host CPU usage has stopped. The microphone works just fine ''before'' the high CPU load in the host. This issue does not occur in VirtualBox 5.1.22, and therefore appears to be a regression (the changelog mentions audio-related changes for better Windows 10 support, so it would make sense).

This issue occurs with both a Linux host (Ubuntu xenial) and a Windows 10 host. The guest was Windows 10 in both cases.

Steps to reproduce this issue:
1. Create an up-to-date Windows 10 guest using Intel HDA as the sound device. The host can be either Windows or Linux since the issue occurs with both. The host should be using VirtualBox 5.1.24.
2. In the guest, right-click the audio icon next to the clock and choose Recording Devices. This shows a volume meter for the microphone. Check to see that the microphone works before proceeding. Do not switch to another tab in the window during the test since that seems to reinitialize the microphone ""connection.""
3. In the host, cause a high CPU load. I did this by running 5 instances of a simple Python script that calculates Fibonacci numbers (attached).
4. After about 10-20 seconds, the volume meter either doesn't respond anymore or stays stuck on a particular volume. Killing/waiting for the Python scripts to terminate doesn't cause the volume meter to start working again. Only switching to another tab and back seems to reinitialize the microphone and fixes the issue temporarily. In 5.1.22, the volume meter never freezes.

It is also possible to test using the Voice Recorder, there I noticed that only a static noise is received after several seconds of high host CPU usage. The easiest way to reproduce, however, is to use the Recording Devices panel.

I have tested using VirtualBox 5.2.0 as well, and the same issue exists there. However, 5.1.24 is the earliest version that has this issue."	ocecaco

Link Position in Buffer (LPIB): Indicates the number of bytes that have been
received off the link. Since this register reflects the number of bytes that have
been received into the current buffer, for the first buffer SDnLPIB will count from
0 to the value in the Cyclic Buffer Length (SDnCBL) register, inclusive. For
subsequent buffers, SNnLPIB will count from a value of 1 to the value in the
Cyclic Buffer Length register, inclusive.

There seems to be a problem with hdaStreamGetTransferSize() such that when LPIB is the same as CBL and the DMA is stopped, it will not restart. I think that hdaStreamGetTransferSize() should behave as if LPIB is 0 when it has the value of CBL.

I'm using an RTOS called INTEGRITY when I encountered this, but I think that this could happen for any guest which stops and restarts the streams. I would think that it is relatively likely that LPIB could be the same as CBL as the natural time to stop the stream would be following an IOC event."	Julian Day

14919	Polycom CX600 gets call from Computeraudio when starting VM with ICH AC97 controller	VirtualBox 5.0.10	defect	2015-12-11T09:07:52Z	2015-12-11T09:07:52Z	2015-12-11T09:07:52Z	"Since VirtualBox-5.0.2-102096 I have a strange behavior with my Polycom CX600 phone connected via USB to the my host system (Windows 7).

As soon as a VM is started and the VM BIOS is loading, the phone shows me silently a call to ""Computeraudio"". Every real call to my phone then only is knocking on like the phone is busy.

As soon I stop the VM, the ""Computeraudio"" call is interrupted and the phone works again like it should.

In VirtualBox-5.0.0-101573 and older versions everything works fine.

Every Version since VirtualBox-5.0.2-102096 have the same behavior, including the actual version VirtualBox-5.0.10-104061.

I tried a little bit around with some settings and found out that this doesn't happen when the audio controller is not set to ""ICH AC97"". Intel HD Audio and SoundBlaster 16 doesn't produce this behavior, but I get no sound out of my Linux guests with these two audio controllers (especially tested with Knoppix LiveDVD 7.6 for repeatable results).

Another check was what happen when I disconnect the phone USB cable from the host.
When the guest was already started and the phone shows already the ""Computeraudio"" call, the call is interrupted as soon as I disconnect the USB cable. After connecting it again, the phone dosn't show the ""Computeraudio"" call again (until reboot the VM).
When I disconnect the cable before starting the VM and plug it in after the VM was started, no ""Computeraudio"" call is shown. The phone works normally.

Because of this behavior starts before the guest OS is loading, I think this is independent of it. Nevertheless I checked out lsusb but there are no USB devices shown, except the input device and the USB root hubs.

I will attach four log files (for Version 5.0.0 and 5.0.2 one with ICH AC97 and one with Intel HD Audio controller). And if it works, also an picture of the phone screen.

11313	Can't assign guest audio to dedicated sound device on Host	VirtualBox 4.2.6	enhancement	2012-12-20T22:40:02Z	2012-12-20T22:40:02Z	2012-12-20T22:40:02Z	"I would like to assign all audio from a Guest into a specific audio device so that my kids can listen to audio on the Guest while I work on the host or other guests. I am using Windows 7 64-bit as Host.

The simplest solution would be to allow the guest audio to be directed to a specific audio device. This is possible using windows APIs, but in absence of choosing a device, VirtualBox sends all audio to ""Default Device"", which is then the same as all other Guests, as well as the Host. Therefore, all audio is mixed into 1 stream, which prevents isolation."	random_luser
11133	On a Windows 8 host VM microphone does not work in an XP guest	VirtualBox 4.2.4	defect	2012-10-27T18:17:10Z	2015-04-03T06:00:37Z	2015-04-03T06:00:37Z	"Host: Windows 8 64, MB ASUS M2N68 AM-PLUS integrated audio

11879	USB microphone unusable in Windows 8 guest	VirtualBox 4.2.12	defect	2013-06-19T12:06:49Z	2015-07-21T04:29:48Z	2015-07-21T04:29:48Z	"With the latest OS X host on a mid 2011 MacMini and Windows 8 32 bit guest, the guest microphone hears loud noise whenever a USB input device (camera or earphones) is selected in host. The only way to get rid of the noise is to set the guest microphone sensitivity to zero. When the line input is selected in the host, the microphone properly hears nothing.

This resembles #5869, but I cannot find the problem in the known issues, so this may be a new bug."	Andrey Gerasimenko
6049	JACK audio support for Virtualbox (Linux host)	VirtualBox 3.1.2	enhancement	2010-01-21T15:16:26Z	2013-04-01T04:56:32Z	2013-04-01T04:56:32Z	"It is difficult to use audio from one or more Virtualbox VMs and other applications simultaniously. Or to route the audio stream between VMs and applications.
Virtualbox currently supports OSS, ALSA and pulseaudio. While the pulseaudio implementation on many distros (Ubuntu) is buggy and difficult to configure, OSS and ALSA usually do not support multiple applications using the audio device at the same time.
I suggest additional support for JACK (Jack Audio Connection Kit). JACK is a well established soundsystem that many (semi)professional audio users use."	mark_orion
4605	Ubuntu Linux guest audio output slow and distorted	VirtualBox 3.0.2	defect	2009-07-22T21:13:53Z	2020-04-22T17:03:35Z	2020-04-22T17:03:35Z	"There's some discussion in community forums related to this, but it doesn't go very far.  Couldn't find any similar report in Bugtracker.  Sorry if I overlooked.

This is an Ubuntu Linux 9.0.4 guest in Virtualbox 3.0.2 r49928 on a Vista SP1 host, a Presario C751 notebook.  Following initial installation of the guest, sound playback works well.  Only after shutting down the VM completely and then restarting will sound playback slow down with a commensurate lowering of pitch as though the clock is running slow.  Sound distortion such as ""chirping"" and stuttering may be evident as well.  The problem is temporarily repaired by reinstalling the Guest Additions and rebooting the VM (reboot only, don't shut it down!).  Having done that, audio playback is restored to normal and will remain normal between reboots of the VM.  Only after the VM is shut down will the problem recur.  The same problem occurred in V 2.2.4 r47978.  FWIW Video output seems to be affected as well.

A Windows XP SP3 guest does not seem to exhibit the same problem.

Using a VM for multimedia apps is silly, but what's amazing is how well it works when it works.  It's not the way to go, but even if you don't, Ubuntu, for example, makes sounds like the drumbeat figure when GDM is ready for login, the Ubuntu ""theme"" as GNOME comes up and other sounds such as error notifications and the like and it is irritating for them to be slow, off pitch and distorted.  More importantly, the fact that it sometimes works and sometimes doesn't implies an underlying problem that may be more significant.

If I can, I will dissect the Guest Additions installation and try to determine what seems to ""fix"" the problem."	Larry Shurr
19984	PulseAudio not working on Fedora 33		defect	2020-10-20T18:53:34Z	2020-10-25T21:57:40Z	2020-10-25T21:57:40Z	"Hi there,
I've been using VirtualBox version 6.1.97 r140489 and r140902 (Q.t 5.6.1) which I compiled myself.
What I noticed is that if I pick PulseAudio on the host, both Windows 10 Enterprise x64 and Windows XP Professional x86 are completely silent and on playback, they fail, with players not showing any kind of progress.
If I choose ALSA, however, audio works, but the guest cannot receive any input from the microphone of the host.
I also tried to make a brand new virtual machine with Win10 and it didn't change, I was able to reproduce the error.
The host is Fedora 33 x64, kernel 5.8.15.
I just wanted to let you know so that you can get it fixed before releasing a new stable version.

By looking at the logs https://pastebin.com/dwYh7C6i it seems that the problem lies here:

14747	No sound. Windows 7 host / Arch Linux guest.		defect	2015-10-26T09:00:58Z	2018-02-28T09:22:23Z	2018-02-28T09:22:23Z	"I have the same problem as described in https://www.virtualbox.org/ticket/14361.

16708	HostAudioNotResponding		defect	2017-04-28T04:52:00Z	2017-05-09T13:56:54Z	2017-05-09T13:56:54Z	"Some AC'97 audio streams (PCM Input, PCM Microphone) could not be opened. Guest applications generating audio output or depending on audio input may hang. Make sure your host audio device is working properly. Check the logfile for error messages of the audio subsystem.

Using the latest test build, Version 5.1.21 r115071 (Qt5.6.1) on Arch Linux.

Audio works, it's ALSA (no PulseAudio), in both the main operating system and Virtualbox.

So why the error?

I've tried using special kernels as I thought it might be a latency issue. No improvement with linux-ck, linux-pf or linux-rt.

Doesn't matter if you use AC 97 or Intel HD Audio drivers."	shillshocked
