#17733 duplicate Linux vboxmanage modifyvm --audioout not working -> duplicate of #17409 Gene77072
Description

I issue the command below and the --audioout parameter is not being processed. All other values for the target machine are set as specified. I can toggle the values for the other fields and see them change on my target VMs. Audio Output shows as Disabled and remains disabled unless I manually change it from the GUI settings in the tray.

vboxmanage modifyvm <mymachinename> --audio pulse --audiocontroller ac97 --audioout on --audioin on

#17726 duplicate Shared folder read errors zxcvgm
Description

File reads from shared folder in the Linux kernel encounters errors. An easy way to test this is with a loop device.

root@VirtualBox:~# dd if=/dev/zero of=/media/sf_z/test.dd count=1024
1024+0 records in
1024+0 records out
524288 bytes (524 kB, 512 KiB) copied, 0.0408967 s, 12.8 MB/s
root@VirtualBox:~# losetup -f /media/sf_z/test.dd

Errors will occur, and the kernel would not be able to identify the partitions because it can't read the image:

There is no problem if the image is copied from the shared folder into the VM first, then using losetup on the copied file.

#17724 invalid Alt and AltGr keys no longer working with mouse integration enabled -> fixed by reconfiguring aha_1980
Description

I had a Windows 7 guest running for some weeks without problems, with both mouse pointer integration and a working German keyboard.

I recently tried to import and use another Windows guest, where I had strange problems getting the keyboard running. I therefore played a bit with turning mouse pointer integration on and off, but didn't succeed and gave up.

Now my problems began: The long time working Windows guest does not accept the Alt and AltGr keys anymore. That is very annoying for me as I need them to get the curly brackets on the German keyboard (I'm C++ programmer, and by the way, Qt contributor ;) ).

Like suggested in [1], the following both work:

  • Pressing Windows+Alt or Windows+AltGr together
  • Disabling mouse pointer integration

But as this had worked perfectly fine before with mouse pointer integration, any chance to get it back?

Thanks
