When I had XP, I found it incredibly easy to get my microphone to pick up good, high quality sound.
However upon getting Vista, I'm having trouble getting it to pick up anything quieter than shouts. I thought I'd fixed it yesterday when playing Team Fortress 2, as it seemed to work, but now it's gone back to its original state, except now all the settings are like they were and can't be put up higher. How do I get my microphone to pick up quieter sounds?
