After changing a hardware and booting up same operating system(archlinux32) on it the sound doesn't work at all. On old hardware it worked well.

When migrated:

1. Booted up a live ISO


2. Ran mkinitcpio -p linux
   


3. Updated /etc/fstab


4. Reinstalled grub

After booting everything works fine except sound.
Also pulseaudio and alsa-utils are installed.

All in all, why could it doesn't show Master or such in alsamixer and doesn't work at all.

This is an old Foxconn 915A03-G-8KS motheboard with single cored Intel(R) Celeron(R) CPU 2.66GHz CPU.

Some good person on IRC channel #archlinux32 helped telling that a solution might be an option for snd-hda-intel kernel module: model=6stack or model=6stack-digout.

So, after reloading this module with option everything worked:

modprobe -r snd-hda-intel
modprobe snd-hda-intel model=6stack

This might be a bug in kernel, so it loads this module without a proper option and, also, a patch doesn't work for that motherboard.

Although, adding this option manually to /etc/modprobe.d/ will tell system to load this module with this option every next boot:

echo "options snd-hda-intel model=6stack" >> /etc/modprobe.d/sound_fix.conf
