Hi there,

Thanks in advance for any help you can provide.

First my OS X version 10.6.7.

A few days ago i was using iMovie and found that my play back on the recordings had VERY LOW AUDIO. i tried it on Photo Book, and there was no audio. I logged out and tried it on another account, same problem. I've been messing around with Audio Midi and System Preferences > Audio and now I really don't know how to repair it.

How do I revert the internal mic to its default settings?
Is there an alternative?

Many thanks!
