Since a couple of days I can get any audio from the microphone into my VMs.
I see in dom0’s pavucontrol that there is sound coming into the microphone as the blue bar moves when I talk. qvm-device mic says the microphone is connected to the VM, but in the VM I don’t see any sound coming in from the microphone pavucontrol or any application.
I have tried with different VMs and different templates (debian-11, fedora-34, debian-sid, …) and I see the same problem. So I assume the problem is in dom0 and not in the VMs itself. Playing sound from the VM works fine and I can hear it so it looks like the pulseaudio of the VMs can talk to dom0.
It was working fine few days ago, I don’t recall doing any changes in dom0 besides doing updates. I do have enabled qubes-dom0-current-testing repo as some times there are fixes from it that help with the many problems of the Intel Tiger Lake I have. But I have tried to reboot the computer with different kernels (5.10.112, 5.16.18, 5.17.5, …) just to check is not a problem of kernel-latest but the same problem persist. I don’t see any clear errors in dmesg neither in dom0 or the VMs.
Any idea where can I look for the source of the problem? What can it be producing it?
