I have a clean install of R4.2 on a machine that had no sound issues using R3.x or R4.0. Most forum posts dealing with sound issues seem to come from update-installs. This was a new install where I chose Fedora templates as the default. There is no sys-audio setup.
I have a combination of new AppVMs based on Fedora 38 XFCE, Debian 12 XFCE, Whonix 17, and some restored Debian 11 and 12 templates from earlier Qubes installs.
Switching the Dom0 Volume Control’s Configuration of the Built-in-audio, I am able to get the speakers to produce some sound, but it is crackly and very faint.
If I plug in headphones to the audio jack, sound is normal, and works fine. The sound will not play properly through the speakers. (I have tried reseating the jack, and re-plugging in the audio adapter)
Occasionally sound plays normally through the speakers. However, I’m unable to reproduce the conditions to restore sound. It sometimes happens when I try playing sound through several AppVMs simultaneously. In those cases, sound is functional until I reboot.
I tried adding kernel-latest and kernel-latest-qubes-vm to Dom0. I’ve tried 6.6.2-1 and 6.6.9-1 kernels without any improvement to the sound.
What are the suggested steps to take to troubleshoot R4.2 sound issues? I didn’t want to try too many of the temporary solutions I found in the forums in case they might make the situation worse.
