Public bug reported:
the builtin microphone doesn't works at all. I have tried to go in
alsamixer to see if the microphone was disabled but alsamixer says: This
sound device does not have any capture controls.
The same happens if I attach a microphone in the jack. Usb microphones
seems to works.
I attach a file generated with checkbox-gui with all test hardware of
the notebooks.
Have a great day
Piviul
