Hi, I tried with the instructions from comment #49 and it almost works
for me.
(You have the kernel versions mixed between 5.3.0-40 and 5.3.0-42 - I
presume that was an accident?)
With Kernel 5.3.0-42 I have no sound at all, and it hangs when I try to shut
down / reboot - might be a different problem.
With Kernel 5.3.0-40 I have sound - just regular stereo as expected, but that
works.
The microphone is detected, but it will not record sound, that is the almost
part.
The funny thing is: If I plug anything into the headset jack - headset
or just plain speakers without a microphone - not only does the output,
and input if it is a headset, work through the jack, but I can also
record from the internal microphone. So the combination stereo speakers
on the headphone jack and internal microphone for recording works.
This is my sound card:
cat /proc/asound/cards
0 [sofsklhdacard ]: sof-skl_hda_car - sof-skl_hda_card
LENOVO-20QD003JGE-ThinkPadX1Carbon7th-20QD003JGE
This is the system info from dmidecode:
Handle 0x0012, DMI type 1, 27 bytes
System Information
Manufacturer: LENOVO
Product Name: 20QD003JGE
Version: ThinkPad X1 Carbon 7th
Is there a trick I am missing, or does the patch still need work?
Happy to provide more info.

Title:
add ucm to make alsa/sof driver work under PA (variants of Lenovo X1
Carbon 7th, Dell cnl and cml machines)
Status in HWE Next:

Bug description:
This ucm is only for Eoan and Bionic, for focal and future versions,
we plan to integrate the ucm2 instead of this ucm, and the ucm2
depends on the alsa-lib-1.2.1 and pluseaudio-v14, the ucm2 is under
developing by the community, is not ready yet.
[Impact]
In the oem project, we have a couple of Lenovo and Dell machines which
connect the digital mic to PCH directly, this design needs the new
sound driver soc/sof, and this driver can't work under pulseaudio
automatically, we need to integrate the ucm for the driver, then the
sof dirver could work under pulseaudio and gnome.
This ucm is maintained by intel audio team, and it is not upstreamed
and will not be upstreamed, since the community is developing the ucm2
which is based on at least alsa-lib-1.2.1 and pulseaudio-v14.0 (still
under developing), for bionic and eoan, we have to integrate this ucm
since the alsa-lib version is too low. For focal and future version, we
are going to integrate the ucm2 after the ucm2 is ready.
This ucm is already verified in the oem project, now it is time to put it
into the stock ubuntu.
[Fix]
These ucm files are backported from sof_ucm1 branch of
https://github.com/thesofproject/alsa-ucm-conf.git
[Test Case]
Boot the eoan kernel or oem-osp1-bionic kernel, then check the log of
pulseaudio, the ucm files are loaded successfully, then check the
gnome-sound-setting, both output and input devices work well.
[Regression Risk]
Low, just add some new ucm files, and this will not affect other machines,
and those new added ucm files are only used by specific machines which enable
the sof driver.
