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!
