it looks like kernel isn't a problem, 'cause it isn't relevant wich

@schmidt,
According to the alsa-info.txt of #33, I couldn't find anything wrong,
the driver already worked and mixer controls already generated. I have
no idea why "the control for sound is gone and hardware keys for sound
doesn't work". With this testing kernel, the audio should work as
before.

If sof driver could load the firmware and tplg successfully, it will not
have freeze issue on waking up. It is weird that your machine has this

@Hui Wang
Thanks for the advice, yes with the snd_hda_intel.dmic_detect=0 bootarg, the
freezes are resolved. The kernel messages contain a lot fewer errors too... So
does this would suggest that the culprit is loading the drivers for the DMIC?

"now I have sound but the control for sound is gone", is it a regression

if you add snd_hda_intel.dmic_detect=0 in the bootargs, does the -46

With kernel -46 sound output is working again, input is still not. The machine
also still freezes on wake from sleep and requires alt+sysreq+B to force a
reboot. Reverting to -40 again for now...
Dmesg attached for troubleshooting.

Notified of update today, and noticed one of the updates was for Kernel
Image 5.3.0-46. So I removed the testdsp SMP kernel today and installed
5.3.0-46 proper kernel: Intel HDA driver not loading (so dummy output).
So I'm back to workaround from 12.
