| #17867 | wontfix | Sound Blaster 16 Synth not working? | ||
| Description |
I've been trying to figure this out for some time. Apparently some SB16 sound works, but other SB16 doesn't. Specifically, the synth does not seem to be implemented. I will use DOS programs as a good example, as I tend to know what they should sound like. For instance, Doom is able to run, and I can hear sound effects, but not the music. So I'm attaching some basic code. This code was originally written in basic, but given the nature of what it did, I was able to convert it to a c function that was compiled and run with a bootloader stub. I tested this on a boot disk in a real machine, and it worked. (The sound way a kind of growl-ly purr that rose, then got quieter, sounds kind of like a vroom, but with a square wave). So this code is OS independent, you just have to call it from a bootloader stub and it should work. When I use it on Virtualbox, it doesn't make any sound, nor does the basic version of it. In fact, the basic version also checks for a sound blaster and can't find one on Virtualbox. So I'm not sure what's going on, but I suspect the synth portion still needs to be implemented? If someone could point me at some code that does something similar for Intel HDA, I'd love to see it, because I wouldn't mind learning how to program for that one instead. |

| #17866 | invalid | Serial Port/UART cannot be used | ||
| Description |
I want to use the UART functionality to communicate with the VM (in this example Linux) from macOS.
As configuration I used The Linux guest says everything is fine: $ dmesg | grep tty [ 0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-4.15.0-23-generic root=LABEL=cloudimg-rootfs ro console=tty1 console=ttyS0 [ 0.000000] Kernel command line: BOOT_IMAGE=/boot/vmlinuz-4.15.0-23-generic root=LABEL=cloudimg-rootfs ro console=tty1 console=ttyS0 [ 0.004000] console [tty1] enabled [ 0.004000] console [ttyS0] enabled [ 1.535605] 00:02: ttyS0 at I/O 0x3f8 (irq = 4, base_baud = 115200) is a 16550A [ 1.721594] 00:03: ttyS1 at I/O 0x2f8 (irq = 3, base_baud = 115200) is a 16550A
The file $ screen /tmp/serial_port2 115200 [screen is terminating] $ cat serial_port2 $ If I run the command as root, screen starts and shows the message Cannot exec 'serial_port2': No such file or directory
If I instead use I also created another VM with uartmode=client, but they also cannot communicate with each other. Is this function not working, or am I doing something wrong? |

| #17861 | fixed | "VBoxManage modifyvm <UUID> --videocap on" doesn't work | ||
| Description |
Since 5.2.x video recording doesn't start together with startvm.
works until VBox 5.1.32 Under VBox 5.2.x the video icon on VBoxGUI is running around, but no *webm file exist. After
the *.webm file is created.
