I want to switch between headphone, headset, mic input/output modes when I
plug in devices. Alsamixer shows two capture channels, one is for the
internal mic. I don't know how to use the other. I've tried switching some
things on and off in hda-analyzer but I failed to get the functionality that
I wanted. This notebook only has one audio port(TRS 3.5mm), so the selection
is vital if I'm going to use an external mic. Currently the port is acting
as an output only port. And something fishy goes on when I select "Analog
Stereo Input" in profiles in Sound Preferences. It lets me use the external
mic through the audio port but only if I push the jack half way, the input
is detected and I can record it(but there's no sound output after I select
this profile, its input only). I some how think that this is the "mic" mode
and if I can get it to work on "headset" mode then I'd be able to use it for
input and output.

This is the information that I got from the script,

Thank you,
