I have the same problem, although a different laptop. I am also using Woody
with 2.4.17 and the CS4281 kernel driver. Sound works fine apart from the
built-in microphone. (The mic works fine in Windows). I have aumix installed
but it will not allow me to turn on the mic for recording. If I use aumix to
turn up the volume for the mic then I get feedback due to the mic and
speaker being close. I've read the sound howto's and googled for answers but
I haven't found anyone who seems to be using their mic on this laptop.

Is this true? I've not tried Alsa yet. I remember reading somewhere that
most laptop sound chips are not full-duplex so recording and playback is not
possible at the same time. Has this anything to do with my problem?
