CS:S on MAC - MacBook Pro internal mic issue

[shakzilla]

Hi guys, first post. Searched around for this, but could only find topics that pertained to boot-camped CS:S games.

I just installed the Mac version of CS:S released yesterday, and I'm liking it so far... Except for the fact that Steam isn't picking up my internal mic. I have a 13" aluminum unibody MacBook Pro.

Any thoughts?

Bump.
Same problem. I get it on alien swarm (VM'ed) as well.
