This is an linux-firmware issue, it's been fixed in next linux-firmware update.
Currently, you can try copying origin firmware under /lib/firmware to make it
work
cd /lib/firmware/intel/sof
sudo ln -s sof-cnl.ri sof-cfl.ri
[4.317419] sof-audio-pci :00:1f.3: hda codecs found, mask 5
I tried options snd-hda-intel index=0 model=laptop-dmic in
/etc/modprobe.d/alsa-base.conf, but it did not work for me.
I tried 5.0.0-1047-oem-osp1, but still not fixed.
Then I tried kernel parameter snd_hda_intel.dmic_detect=0, which fixes
the sound output, but the internal microphone now
I could not login with 5.0.0-1040-oem-osp1 except ubuntu with wayland
(still no sound) so I added following line to /etc/modprobe.d/alsa-
base.conf
options snd-hda-intel index=0 model=laptop-dmic
This setting works with 5.0.0-1043 and 46 kernels.
Unfortunately internal mic. does not work as
not fixed with 5.0.0-1046-oem-osp1, reverting back to 5.0.0-1040-oem-
osp1

Both 5.0.0-1043-oem-osp1 and 5.3.0-42 have the problem.
