Public bug reported:

I'm using an acer Aspire v nitro. Since the kernel upgrade to 13.0-27,
shutting down the computer leads to a kernel panic. kernel 11 still
works fine. The problem first appeared around 3 weeks ago.

As far as we could tell, something's up with the sound driver,
snd_hda_intel. I've been having problems with my sound driver/ sound
card for a year now, It doesn't recognize the internal speaker (with no
other hardware connected, the only option is dummy audio output) and
microphones. my workaround is bluetooth speakers or headsets/
microphones that come with their own soundcard.
