Please add "options snd-hda-intel dmic_detect=0" in the /etc/modprobe.d
/alsa-base.conf, then the legacy hda driver will work as before.
I am working on it, will fix it soon.

Bug description:
The sof-pci-dev and snd-soc-skl all contains the same pciid, if
the soc-skl is loaded ahead of sof-pci-dev, the sof driver will
not work anymore, in the oem project, we manually put the soc-skl
in the blacklist.
From kernel-5.4 (focal kernel), the driver soc-skl is disabled by
default, and there is no users report any issues on it. So let us
disable soc-skl in the eoan and osp1 kernel too.
The patch for eoan kernel doesn't remove the modules because looks
like the abi folder are not controlled by git. This will break the
modulecheck, so if this patch could be merged, please help remove
those modules:
snd-soc-skl
snd-soc-skl-ipc
snd-soc-skl-ssp-clk
[Impact]
If soc-skl driver is loaded ahead of sof driver, the sof could
not work anymore, we need to blacklist the soc-skl manually
[Fix]
Like the focal kernel, we disable the soc_skl driver in the kernel
config
[Test Case]
Tested on Lenovo and Dell machines which has dmic, the sof driver
could be loaded successfully.
Tested on the machinces without the dmic, the legacy hda driver
worked well as before.
[Regression Risk]
Low, Focal kernel and mainine-5.5, 5.6-rc kernel all disabled this
dirver; and We have not met a machine need the soc_skl driver yet;
and Intel claim that the sof could replace the soc_skl driver.
Probably a kernel bug.
The sound card isn't detected in 5.3.0-41-generic
Booting 5.3.0-40-generic does work.
The relevant dmesg message is:
