F31 requires to install latest alsa-firmware, alsa-ucm and pulseaudio packages
for this hardware. Anyway, the hang looks suspicious. Create a Fedora bug for
this with the kernel log. I'll check.

I hope i put it in the right place...

Here is the journalctl dump.
last boot was 5.5.8 with alsa.conf
previous was 5.4.19 without alsa.conf
previous was 5.5.8 without alsa.cong and hang

Do you need something else?
