Skype mic problem, my voice sounds very faint...

But everything else is working fine. I can hear the people on the other end great. But speaking into my mic is the problem. I can hear myself on the sound test, but just barely. It is a very faint voice. I've checked all the settings and everything is how it should be. Nothing wrong with the mic itself, either.

Any ideas? Thanks.

I know you said there's nothing wrong with the mic, but the first thing I would try is a different mic.
