Hi Johannes,
I have been wanting the exact same thing on my laptop, so I have been
digging around in the hda code.
I have got to the point where I can use the headset mic, but I have to
manually switch from the internal one.
There is no configuration magic, I had to patch the driver.
It seems nearly impossible to find docs on Realtek codecs, I have looked
at what Linux does in their driver.
They change some mysterious registers in the codec, so I my patch just
does the same.
Which codec do you have? I have the ALC283 ('cat /dev/sndstat' should
tell you)
