I have found similar issues but with a different drivers. Any idea about where to start debugging?
I have intermediate Linux knowledge but I am not an expert.
End-of-life kernel, you should switch to 5.4 or 5.10.
As for the audio, I suggest you try installing sof-firmware, and then rebooting. If that doesn’t work, post the output of sudo dmesg | egrep -i '(hda|snd|sof|audio|alsa)'.
