Bug description:
Recently, external microphone has stopped working while using classic
wired audio combo jack headset.

Basics:

1) Headset's microphone works fine both in MS Windows on the same machine and on older Xubuntu on another machine.
2) Internal laptop mic works normally.
3) Yes, I have mic unmuted in settings.

I've followed whole step1 from this troubleshoot guide:
https://help.ubuntu.com/community/SoundTroubleshootingProcedure

Did not help.
