Hi!
Did you have a look at howmany capture_* ports there are? Perhaps there are
special ports for microphone?
Did you check with simple alsa-tools? arecord or something like it, to see
if ALSA handles it?
Are you 100% sure your connecting cables are all right? Don't laugh, I had
that ones and wouldn't believe it. :-(
Did you try the mixer anyway? alsamixer or alsamixergui?
That's all I'd have.
Kindest regards
Julien
