[alsa-devel] Microphone dead: Gateway MX6543, hda-intel, STAC925x

[Zoran Rilak]

Hello,

    I've searched the archives and haven't found a solution for this
particular model (STAC9250).  Front mic does not work.  I have tried
other models, aside from m2-2, and all four possible values for
position_fix as well, but to no avail.  

    If anyone is willing to tackle this, please point me to what other
information I should provide in order to get to the bottom of this.  I
am using Ubuntu kernel 2.6.22-14  and ALSA 1.0.15 compiled from source.

Here are my /proc/asound/card0/codec#* files:
