[Solved] No sound after kernel update to 5.6.2 (sof-hda-dsp)

My configuration (Lenovo X1 Carbon gen 7) used to work before update to kernel 5.6.2 (following Wiki indications).

Now it is not working anymore, with or without Wiki changes.

Alsa still sees the card:

$ aplay -l

card 0: sofhdadsp [sof-hda-dsp], device 0: HDA Analog (*) []
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: sofhdadsp [sof-hda-dsp], device 1: HDA Digital (*) []
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: sofhdadsp [sof-hda-dsp], device 3: HDMI1 (*) []
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: sofhdadsp [sof-hda-dsp], device 4: HDMI2 (*) []
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: sofhdadsp [sof-hda-dsp], device 5: HDMI3 (*) []
  Subdevices: 1/1
  Subdevice #0: subdevice #0

but cannot access it:

$ amixer
amixer: Mixer default load error: Invalid argument

(same thing for amixer -c0).

In turn, this cascades into multiple errors leading to pulseaudio crashing (I'm putting that for search engine discoverability):

$ sudo journalctl

I want to stress again that the same configuration was working well in the previous kernel: I even downgraded it to test and sound is working again. I tried to activate testing repos, to no avail.

Does anybody have an idea? Could it be a mismatch between the kernel and alsa versions?

Edit: Update to 5.6.3 solved the issues. Even better, it looks like the workarounds from the wiki became unnecessary.

Re: [Solved] No sound after kernel update to 5.6.2 (sof-hda-dsp)

It is similar with me, but it is sound but quiet, alsamixer not working.
I recompiled alsa-lib, alsa-plugins and alsa-utils, but it didn't help.
Someone has already reported a bug:
