[alsa-devel] Apple iMac pin configs

[Ivan N. Zlatev]

Hello,

I have a 20'' iMac machine with a hda-intel (SigmaTel 9221 A1 codec)
and I have successfully been using the mac mini pin config, but there
is one problem - the microphone doesn't work. The machine has a
built-in microphone, built-in speakers, 1 digitial out jack and 1 for
headphones. With the mac mini pin config I get 2 mics: "Front Mic" and
"Mic" but none of those works. (alsamixer-macmini.gz for info).

Today I spent some time on the search for the the correct pin
configuration and it should be this [1] according to the windows
drivers. This configuration causes amixer.gz, basically 1 "Mic" (which
again doesn't record), but also "Mic as Output" and "Line in as
output" (I don't have a line in as far as i know). I have also tried
the macbook-pro and macbook introduced with 1.0.14rc3, but the mic
doesn't work.

I have attached
  * cat /proc/asound/card0/codec#0
  * Mac OS X's complete dump of information of the audio driver -
imac20-ioreg-audio.gz
  * amixer with the below config and the one with the macmini pin config

Can you possible assist me to get the below pin config in tune, so
that everything works?

Regards.
