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. ** Bug watch added: github.com/thesofproject/linux/issues #1877 https://github.com/thesofproject/linux/issues/1877 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1859246 Title: Built in audio speakers/earphones + microphone + SPDIF not activated.
