If you are talking about the little microphone top-right of the screen:
IIRC you will have to wait for the 2.6 kernels with alsa since dmasound
isn't supporting recording (I guess externel USB Microphones won't work
either).
Concerning a broken sound which here is sometimes caused by quake2 I
simply reload the soundmodules (rmmod..insmod) via a script and
everything is back (also I sometimes have to kill the app that is using
dsp [fuser /dev/dsp]).
