I read in the wiki that the sound issues have to be filed against "linux", changed from ubuntu-release-upgrade

** Package changed: ubuntu-release-upgrader (Ubuntu) => linux (Ubuntu)

Title:
  No sound from internal card chtmax98090 Bay Trail QWAWKS

Status in linux package in Ubuntu:
  New

Bug description:
  Asus C300 (repurposed chromembook - bios flashed by Mr.Chromebox script)  - Kubuntu Focal minimal fresh installation.
  The sound card is detected: I see it in the Plasma Widget, in pavucontrol, in alsamixer and it's not muted.
  I tried and add in /usr/share/alsa/ucm/chtmax98090/ the old style use case config files: no success.
  I tried and unmute speakers left and right in alsamixer: no success.

  I rapidly tested Ubuntu Mate Focal fresh install: I had exactly the
  same issue.

  I'm running on the same rig Debian Bullseye, kernel 5.4: sound card
  output and input are both working perfectly - I noticed that in
  Kubuntu alsamixer Kubuntu when I open it I have an entry HDA IntelPCH
  (the HDMI card), while in Debian I find Pulseaudio.

  
  I attach the alsa-info.sh output.
