Okay, I have two problems. The first one is that my mic won't work, I have everything turned up to the maximum settings and everything, nothing is on mute, but it won't work with Ventrillo! I've had three mics so far, none of them have been working on this new PC, it uses Vista, if that matters.

The second problem is that while playing games the surround sound is reversed. If something is making noise to the left of me in the game, I hear it in my right ear, and vice versa. I have surround sound speakers too, could they be interfering with each other?
