I have a workaorund and a fix for this bug.
The bug is due to missing UCM2 folders and config files, which are now
available on git hub.
The missing folders are:
- /usr/share/alsa/ucm2/chtmax98090/ : it can be retrieved from
https://github.com/alsa-project/alsa-ucm-conf/tree/master/ucm2/chtmax98
The package involved is alsa-ucm-conf, version 1.2.2
It does not contain the UCM2 configuration files for the sound card
chtmax98090, which have been added upstream.
Because groovy has alsa-ucm-conf 1.2.2, the bug is applicable for 20.10 too.
In Debian unstable and testing is available alsa-ucm-co
I manually installed alsa-ucm-conf 1.2.3 from Debian testing on Focal:
it works perfectly.

Agreed, your backport in 1.2.2 testingvis working as well as the 1.2.3 from
Debian Bullseye.
It definitively makes sense to submit the 1.2.2 testing to the Ubuntu

Do I need to file a bug against Groovy same issue or is the 1.2.2 is
automatically included in Groovy too?

Ok thanks.
Last night I re installed from scratch Ubuntu 20.04.1 and I noted a
variation: to make the sound to work I needed to add your testing repo

I have the same problem, I thought it was related to plugging/unplugging the
headset jack (see comment #28 and following ones).
Hui's and my opinion is the it's not alsa-ucm-conf related, therefore
this requires more analysis and a new bug report.

This setup seems to fix the issue, however the test I did is too short

In my case volume levels are good on both 20.10 and 20.04.
Consider that the alsa-ucm-conf parameters upstream for chtmax98090 are based
on my hardware.
