[An advice from Mac users: Lion or not Lion?]

After installing Moutain Lion, I had problem with voice, the mic didn't work.

After trying lots of tips and tricks, I found that uncheck the "media filter" in the sound preference panel in Firestorm worked for me. 

Now my voice works again. Hope it will help others, maybe...
