My average workspace uses 10 VMs, of which 6 are Whonix-related.
The 4 Fedora21 VMs currently have proper audio, although looks like there was an issue in the past:
Occasioanlly, in some rare cases, sound does not work in a VM · Issue #787 · QubesOS/qubes-issues · GitHub : (Occasioanlly, in some rare cases, sound does not work in a VM)
Of the 6 Whonix VMs, 3 had audio (VM Manager ‘Attach/Detach Audio Input…’ enabled) on 1 run, 2 on 2nd reboot, 3 on 3rd reboot. Shutting down and restarting VM does not solve. Rebooting the entire machine seems to have some effect that’s not completely random but I havent been able to identify.
To confirm no audio, ‘pactl list’ shows Sink #0 Name: auto_null instead of vchan_output.
Running ‘pactl -nF /etc/pulse/qubes-default.pa’ restores audio for the current session but does not persist. It seems on VM startup, the qubes-default.pa is not running as it is supposed to.
Perhaps, related issues:

I can’t tell if this issue is related to any prior links because I don’t know how to view these past commits, such as:
