I’ve recently upgraded to the testing 4.2 release and the audio is playing up, where I will have audio initially upon boot, and then when I open a different VM and try to play something I will have no audio across all VM’s. I’m running KDE plasma.
This also results in video embeds freezing in place, so embedded video will not play also.
When I unplug and replug-in the headphones jack I get sound back sometimes. This is only temporary and the problem will repeat itself shortly thereafter. This issue is also temporarily fixed by going in to pulseaudiocontroller and manually changing the output mode to a different one and back again. It appears to default to “Analog stereo duplex” but the issue arises when I set it to “analog stereo output” also.
When I grep journalctl for audio, some things that stand out are:
"no output name for alsa_output.pci(numbers).analog-stereo and the same message for "analog-stereo.monitor. reference error: source model is not defined failed to create sink input: sink is suspended
From pulseaudio -v
error opening pcm device hdmi… UCM is not supported for this HDM model
I also do not have an internal microphone attached, i removed it.
Should I follow this and install pipewire-pulseaudio in my template VM’s? V4.2 Pipewire Installation - #2 by dro212
I have made an effort to troubleshoot this before posting here online using the archlinux page on pulseaudio troubleshooting etc. but I can’t find a thread I’m capable of chasing down. Help would be appreciated.
