[Alsa-user] macbookair1,1 microphones

[Nicolo' <nic...@gm...>]

hello, i have microphones (both internal and external) not working on a mba.
this is the result of alsa script
http://www.alsa-project.org/db/?f=bc96743cc602b4f03ef3c304e56ad3fe80047564
up to now, i've tried changing the value in /etc/modprobe.d/alsa-base.conf of
options snd-hda-intel model=auto,mbp3,intel-mac-auto,lenovo-101e
and playing with alsamixer, with no success.
i check with arecord -d 5 and aplay.
can anyone help?
best,n
