At your inspiration, I upgraded my Powerbook Pismo to 2.6.5-gentoo-r1 
and Alsa 1.0.5 to see if it worked for me. It did, *but* I had to 
downgrade jack to 0.94 to get it working! NO settings, manual or in 
Qjackctl, would get anything but a segfault with jack 0.98. So you might 
try that...

My jack incantation this time was:

jackd -d alsa -d hw -S -r 44100 -p 4096

Still no sound in however, just noise, and the only control worth 
messing with in alsamixer is the one for "PC Speaker".

You never did mention what Mac you are trying this on. You might get 
better help with a bit more info on your setup ;-) Also, you might 
consider trying an external soundcard, even if it's only one of those 
silly little USB IMics.
