Audio high/low pitched?

I can’t reproduce this issue on my other 2 ubuntu vbox VM’s, so it seems to be specific to whonix. When I’m playing short videos on VLC or MPV inside whonix 16.0.8.2 for vbox, I notice videos will a lot of times either be high pitched or low pitched until I restart the VM (it can take several restarts before the pitch issue goes away). I’ve tried from 10gb of RAM to 2gb of ram allocated to the VM and 2-3 CPUs allocated, but it doesn’t seem to have an effect.

Also had this issue on older whonix versions as well.

Whonix doesn’t change sound settings inside the VMs. I don’t remember anything related changing in Whonix source code. Debian, VirtualBox and/or the Linux kernel might have had related changes that I am not aware of.

You could try changing the VirtualBox host software sound audio settings.

See VirtualBox documentation:
https://docs.oracle.com/en/virtualization/virtualbox/6.0/user/settings-audio.html

Try changing:

  • Host Audio Driver
  • Audio Controller

Compare the audio setting with VMs where this isn’t happening.

Please let me know if you find some settings where this issue doesn’t happen.
