Public bug reported:
The mic works well with Ubuntu 12.04 but not with newer versions. I've try with
14.04, 16.04 and 17.04.
I've try to compile last alsa-lib (1.1.4.1), alsa-tools (1.1.3) and also-utils
(1.1.4) versions but mic doesn't works with them.
Mic is correctly discovered by system (When I plug the jack it appears in
System Sound GUI), but it doesn't record anything.
