Also using a Lenovo X1 7th generation. I can confirm that everything
works using 5.3.0-20. I suspect that I've compared to Joel above me,
taken a few extra steps:
* Added snd_hda_intel and snd_soc_skl to /etc/modprobe/blacklist.conf
* Added the alsa-ucm files from [1] to /usr/share/alsa/ucm/sof-
skl_hda_card
* Added this sof topology file [2] from a Lenovo employee to
/usr/lib/firmware/intel/sof-tplg
I have the following devices displayed using `arecord -l`

I need to select in Pulseaudio the `DMIC stereo` input to get working
microphone. I did have to boost most of the channels in alsamixer record
to get acceptable recording level. If I select the "Cannon Point-LP High
Definition Audio Controller" I get nothing.
I can also list all pulseaudio sinks and alsa playback devices if you
like. Notably all HDMI/DP channels show up.
So once again, both playback and the DMIC work with the 5.3.0-20. But
only if you manual update the ALSA-ucm files, blacklist the modules. It
could be that the Lenovo provided topology file is not required.

Title:
eoan: alsa/sof: Enable SOF_HDA link and codec
Status in linux package in Ubuntu:
Fix Committed
Status in linux source package in Eoan:
Fix Committed
Bug description:
[Impact]
We tested the EOAN kernel on the LENOVO or Dell machines which have
dmic directly connnected to PCH, the dmic didn't work.
[Fix]
We need to enable SOF_HDA link and codec, then the sof driver
and Legacy HDA driver work together to make the dmic work.
[Test Case]
Install the latest 19.10 image, build a new kernel with this
patch and replace the existing kernel, After installing the blacklist
package (blacklist snd_hda_intel and snd_soc_skl) and ucm package,
the dmic and all output devices (speaker/hdmi) work.
[Regression Risk]
Low, these configs are already enabled in the oem-b-osp1 kernel
for a long time, and we tested it on many lenovo/dell machines witch
have or have no dmic, all worked well.
