Sound issue with 4.1.2

Hello,

Everything was going smoothly until a few days ago. Now, I have sound freezing issues, with sounds artefacts or just no sound in my qubes. It may be related to a dom0 update (everything is up to date), but I am not certain.
My kernel is 5.15.94-1.
The audio device is an AMD Navi 10 (HDMI on Radeon RX 5700 XT).

The XFCE widget lost its direct control over the sounds card, but I can access its parameters with volume control or alsamixer. When I play with the volume or the sound card selection, I may get my sound back.

I found many lines similar to the following in my logs:

Any idea? Thank you for your help!

Strange issue. It happened again after a reboot or two, but not since.

Sometimes, after a reboot, I have to manually select my soundcard because another (or nothing) is selected by default, but I had no sound artefact for a week. And nothing in my logs.

I tried to change the HDMI cable just in case, but I think it was fixed before I did. Before Qubes, I was on Arch for two years with this config and everything was ok, so I guess it is software related.

Fingers crossed!
