I tried updating libasound2(-data), pulseaudio and kernel to 5.3.0-46 (not
oem!) in my Mint 19.3 Box (Bionic). Also removed manual changes like blacklist
snd_hda_intel and snd_soc_skl and also removed the "ucm" added by the script i
found on github (posted above) from
@ash,
OK, got it, will track this issue with that bug.

Please open a new bug to track it. The solution in the github is for
ucm1, now 20.04 uses ucm2, we need to wait for the ucm2 solution from
upstream, to make the bass speaker work is easy, but to make it work
under alsa-lib, pulseaudio and gnome is not easy, so upstream is still
working on it.

Hi,
may i ask if the bass speaker will also sometimes be supported in Focal?
Currently iam using Mint 19.3 (18.04 with 5.3.0-40 kernel and sof firmware)

(https://gist.github.com/hamidzr/dd81e429dc86f4327ded7a2030e7d7d9).
With that all 4 speakers

To manage
About the hdmi audio on the dock, with the current kernel, it can't
work. And Intel is working on it, kernel patches are ready, but they
need to modify the ucm. After they finish them, we will integrate them
into the ubuntu linux.
Please wait for 1 month or about 2 months.

Thanks @Hui, @Shengyao
Using 5.3.0-21-generic from proposed, the ucm config files (via
ppa:xueshengyao/dmic), and blacklisting snd_hda_intel and snd_soc_skl,
both speaker and HDMI audio out work. (related:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1848490)
Apologies if this is off
the package oem-dmic-sof-lp1825294 contains the UCM config files for
this audio device, right now, this PPA is the best and easy way to use
it. In future, we may add this UCM to a package in the official Ubuntu
archive, but no clear plan yet.

Can you clarify: are you saying that installing that oem-dmic-sof-

or that you're asking us to test if that package solves the problem
before the change is incorporated into the official Ubuntu kernel?

This issue is going to be fixed on 19.10 (Eoan) together with internal
mic issue (dmic issue).
Please wait for the 5.3.0-20-generic kernel or later ones, then install an
package:
sudo add-apt-repository ppa:xueshengyao/dmic
sudo apt-get update
sudo apt install oem-dmic-sof-lp1825294
reboot
Then
Same here (19.10). A workaround could be to use software volume control
by placing the following in /etc/pulse/default.pa:
load-module module-alsa-sink control=PCM
