Description of problem: There is no sound audible when running a F36 KDE Desktop in a libvirt based VM on Fedora 36 Workstation. The sound playing applications do not report any problems and their VU meters and progress bars do normally proceed as if the files were playing just fine. I have tried with OGGs and WAVs and various applications - Elise, Dragon Player, Gnome Music (from Flatpak) and the result is still the same -> no audible sound. When trying this with a F36 Workstation libvirt VM, sound can be played normally without any issues. Both VMs use the same sound driver -> HDA (ICH9) Version-Release number of selected component (if applicable): plasma-desktop-5.24.0-1 (VM) libvirt-8.0.0-2.fc36.x86_64 (host) How reproducible: Always Steps to Reproduce: 1. Boot KDE Live and install it to the disk. 2. Start the system. 3. Try to play some audio files. Actual results: No sound is heard when played on libvirt based KDE VM. Expected results: Sound should be heard normally as it is on libvirt based Workstation VM.
I have also tested on bare metal and there, the sound is ok.
Created attachment 1862925 [details] Journalctl .-e from the affected machine. There are some wireplumber errors in the logs but I am not sure if these affect the behaviour somehow.
