Built in audio speakers/earphones + microphone + SPDIF not activated.

[Gunne Steen]

Only audio through HDMI activated and working.

Ubuntu is 20.04 LTS, but issue with audio is the same independent of Ubuntu release in use.

I don't know if https://askubuntu.com/questions/1213271/microphone-does-not-work-on-new-dell-inspiron-7590/1220414#1220414 is helpful. It is my post on "ask ubuntu" to help others, as I managed to make sound working on my laptop.

Notes
1) Sound is working using sof
2) sof configuration files are not in master branch of github:thesofproject/alsa-ucm-conf
3) 5.3.0-42, breaks sof again.
4) https://github.com/thesofproject/linux/issues/1877 here a discussion is opened for the 5.3.0-42 issues also.

I'm new to all these but if I can help in any way I can try.

For kernel 5.5.x I also found https://github.com/thesofproject/linux/issues/1917
