Macbook microphone not working

It seems that the Macbook wiki page is missing a quick how-to for microphone setup.  Have any other macbook users had any success?

I've followed the ALSA wiki page and installed/configured alsa-lib, alsa-utils (but did not install alsa-oss).  I am able to hear audio from the speakers, it is just the built-in microphone that is not working.  It works fine in OS X, so it is not a hardware issue.  I've unmuted the channels and my ALSA config is as follows:

Master 100 [ENABLED]
Front 100 [ENABLED]
Surround 100 [ENABLED]
Center 100 [ENABLED]
LFE 100
Side 100 [ENABLED]
Line in as Output [OFF]
Mic as Output [OFF]
IEC958 [OFF]
IEC958 Default PCM [ON]
Capture 100 [ON]
Capture 1 100 [ON]
Input Source [Mic]
Input Source 1 [Line]
Mux 100 [ON]
Mux 1 100 [ON]
Swap Center/LFE [OFF]

Re: Macbook microphone not working

It works for me out of a box (with Macbook Pro 3.1). You can try this:

bash-3.2# alsaconf

Strange, alsaconf seemed to work the second time, thanks!
