I thought the fix will be merged to ubuntu kernel automatically with the
stable patches. Since this doesn't happen, I will backport it to ubuntu
kernel.

Yeah!
I hope this will be backported into 5.4 for Ubuntu 20.04.

I don't think the fix has been back-ported to 5.4 kernel.
The upstream kernel fix was included in kernel 5.8-rc1 and later:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/sound?h=v5.8-rc4=89d73ccab20a684d8446cea4d8ac6a2608c8d390
I tested with the 5.8-rc1 mainline

Hi!
The latest kernel in 20.04 (as today) is 5.4.0-40.
It does not work, no sound on this kernel version, Dummy output only.

OK, This is my PR https://github.com/thesofproject/linux/pull/2146, and
Intel also found this issue and had a PR
https://github.com/thesofproject/linux/pull/2122
So finally a fix will be upstreamed to mainline kernel.

Here is alsa-info.sh output with snd_hda_intel.dmic_detect=0

With dmic_detect=0 internal speakers works but internal mic does not.
External headset works fine both headphones and mic.

@lurii,
Looks like the 1st error is "sof-audio-pci :00:1f.3: error: codec #0
probe error, ret: -2", so it means it fails to initialize your analogue
codec driver.
I never met this issue before, could you please add dmic_detect=0 to
make sure audio works, then generate an alsa-info.txt and
I finally managed to disable secure boot.
No changes to the audio, logs are the same.
