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:
