[SOLVED] built-in audio doesn't work

Looks like after an update my built-in audio had stopped working.
I checked dmesg and it showed that I have problem with soh drivers. I've installed them:

sudo pacman -S sof-firmware sof-tools

The errors in dmesg has disappeared but still no built-in audio is working (despite everything is okay with headphones).

Audio:

Audio device: Intel Corporation Comet Lake PCH-LP cAVS (prog-if 80)

pacmd list-sink-inputs

says that the audio is not muted.

alsamixer -c 0

also looks right

pavucontrol

- looks like everything is working, the Silence in the Playback tab is active. The same goes for Output Devices tab. I've tried different combinations in the configuration tab, but still nothing works.

audio dmesg:

Re: [SOLVED] built-in audio doesn't work

It turned out that the audio card wasn't detected by the system. There was only loopback one. I've added

snd-intel-dspcfg.dsp_driver=1

to /boot/grub/grub.cfg on the 'linux' line and it works now.
