What program are you using to test the microphone? Several
applications still use the older OSS instead of the newer ALSA
interface, especially for microphones. ALSA includes OSS
compatibility, but the mixer levels are somewhat separate. Try using
an OSS mixer program, like rexima or aumix, as well as alsamixer, and
make sure that both the OSS & ALSA mixers are set to record from the
microphone & the capture level isn't 0. Also note that in alsamixer
there are separate playback & capture levels for the microphone, as
indicated in the "View:" line towards the top: pressing tab should
cycle them.

Good luck,
