[alsa-devel] probing state of high definition audio card in windows / SigmaTel STAC9221 microphone problems

Hi, I am struggling to get the (external) microphone working on a
SigmaTel STAC9221 A1 device on my Dell XPS M1210 laptop. I saw other
emails indicating that this was still problematic, and the latest
drivers from alsa 1.0.14 did not seem to fix the problem.
So now that I've started reading and trying to understand the basics
behind the hda codec in an effort to fix this problem, I was wondering
if it was possible for me to boot into windows (I've got a dual-boot
setup), get into a state where the microphone is working, and somehow
probe the codec's state at that time (all of the pin configurations,
etc.)... then theoretically, if I reproduce that configuration on the
linux side, it should work (right?).
So the question is, does anyone have a ready-made utility for Windows to
do this probe of the high definition audio codec? I could probably try
writing one myself, but thought I'd check if it already exists.
Please send responses by email too (not subscribed).
