[arch-general] Arch Linux accessibility install: audio doesn't work!

[Uwe Koloska]

Hello John,

there seems to be some regression in kernel 5.13 that is triggered on 
(some) boards with intel hda sound of newest version like yours.

With `cat /proc/asound/cards` you could test, if your card is recognized 
from the kernel. For me the fist soundcard slot was just empty (the 
second one was HDMI and that should be the same for you).

If this is the case you could try with different parameters to the 
intel_hda driver. For me the parameter `probe_mask=1` has solved the 
problem. In the kernel documentation there is some info about this 
parameters for intel_hda:
   https://www.kernel.org/doc/html/latest/sound/hd-audio/notes.html

You can test the solution without reboot. Just unload the kernel sound 
modul and reload with the right parameter:

   sudo modprobe -r snd_hda_intel
   sudo modprobe snd_hda_intel probe_mask=1

If this really solves your problem, you could make the solution 
permanent with this modprobe configuration file:

   echo "options snd-hda-intel probe_mask=1" \
     | sudo tee /etc/modprobe.d/sound.conf

Hope this helps
Uwe
