Recently, external microphone has stopped working while using classic wired audio combo jack headset.
And worse, I've tried now fresh Ubuntu 20.10 USB live, and not working, either.
- Headset's microphone works fine both in MS Windows on the same machine and on older Xubuntu on another machine.
- Internal laptop mic works normally.
- Yes, I have mic unmuted in settings.
there is only one profile in pavucontrol: whereas on my older machine with Xubuntu there are many more and I had been used to switch between "Analog Stereo Duplex" and "Analog Stereo output" to actually mute all mics in a convenient way.
There is no
amixerby the external microphone:

What does not work:
This recommendation (
killall pulseaudio && pulseaudio -k && rm -r ~/.config/pulse/* ; rm -r ~/.pulse* ; sleep 10 && reboot) from help.ubuntu.com has not helped.
Hardware and OS info:

How to fix this?
I believe the very same headset used to work just fine in 20.04.
What to do, please?
