For some reason I can't get the internal mic on my iMac to work. I went through the system settings to select built in microphone and when I open up garageband and have an active real instrument track open (mic input selected), I get a weird static. When I hit the speaker volume increase and decrease buttons I get a weird short high pitched squeal. I tried plugging in my audio interface to see if that mic is working, and its just fine. I even reset my PRAM and NVRAM. What's the matter with my internal mic and what can I do to fix it?

Sounds like you went through the basics.... you can test it in system preferences... see if it picks up anything... if not... might be time to just cab it to one of the NYC stores, just be sure to make an appointment online first. (just visited the upper westside one.... REALLY nice)

Try repairing disk permissions? Sometimes something (especially Flash if you've used an online plugin that uses the mic) fools around with it.
