I then restarted the computer and selected the 5.10.0-1035-oem kernel provided by Chris.
Now, not only the sound output works as expected from internal speakers, but the internal microphone works as well! I can also plug headsets using the Jack output and the sound is output as expected.
I attach pulseaudio logs for reference (without any headset connected).
Following a discussion with Chris, I checked /usr/share/ alsa/ucm2/ and discovered that /usr/share/ alsa/ucm2/ hda-dsp/ was missing.
I created it and put the files from https:/ /github. com/alsa- project/ alsa-ucm- conf/tree/ master/ ucm2/hda- dsp in it.
