After upgrade (fresh install) to R4.2.2 (Linux dom0 6.9.7-1.qubes.fc37.x86_64) I’m with no sound 
- for creating audio qube I used Ben’s SALT files which I found in this detailed howto
I think setting up necessary templates and appVMs went without issues:
$ systemctl --user status pipewire

But there is no sound in sys-audio (disp-sys-audio) itself:

Did anyone managed to get sound working on NV41 with R4.2?
Please let me know
