nikgnomicradio,
agreed fully!
1.
Today I can manage with PCH drivers and headphone mic.
2.
Hopefully sndhsdpa gets fixed in kernel some day. Now inside mic works, but jack server refuses to co-operate.

Many thanks for good discussions!

Learned later, that this line
options snd-intel-dspcfg dsp_drivers=1
was added to /etc/modprobe.d/alsa-base.conf

Nice, but now microphone was muted. There is nothing in Settings/Sound/input drvices.

Accidentally: hw:sofhdadsp turned in my laptop to hw:PCH This happened for instance in Qjackctl / Output device and Input device boxes. Jack server now starts! Also jackd -d alsa -d hw:0 now starts Jack. [Solved] But what actually happened? I would like to understand, as one more "Cannon Point-...

Installed the "low latency kernel" 5.7. No luck.

Thanks khz!
Unfortunately jack still fails to start.
D-bus error disappeared, but this remains:
Could not connect to
JACK server as client.
Overall operation failed

Thank you folks for new ideas!

For a week ago, I installed that ubuntustudio-installer, put Jack still doesnt start. I even checked Ubuntu Studio using a live USB stick. Jack still fails.

Perhaps I should try that low latency kernel?
