alsa-ucm-conf)

Bug description:
[Impact]
There is no ucm for ASUS C300 in the 20.04 and 20.10, as a result,
the audio doesn't work on this machine after installing the 20.04 or
20.10.
[Fix]
The ucm files for this machine are in the alsa-ucm-conf 1.2.3,
cherry-pick them to ubuntu 20.04 and 20.10
[Test Case]
After booting up, use speaker to play some sound, it works well,
plug a headset, play sound to headphone, it basically works but has
some crankling noise, it is a kernel issue for this noise.
[Regression Risk]
This SRU adds new ucm files, If the machine uses the audio driver
of chtmax98090, it will apply this new added ucm files, there will
be speaker/headphone in the UI. So the possible regression is with
this SRU, users could see the audio devices in the UI but the audio
doesn't work (without this SRU, users couldn't see the audio devices
in the UI at all and the audio doesn't work). This possibility is
low since we tested it on the ASUS C300.
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.
