For some strange reason I can go across the hall in my house and plug any of the 3 microphones i have into my brothers computer and they work perfectly. His computer runs windows xp. When i try it on my computer with vista.....nothing, no sound is recorded. This is kind of wierd because when i configure my sound next to the microphone icon ill see a bar and it moves up and down according to me making sound....so the microphone is picking up sound its just not doing anything with it. Anyone else having troubles like these?
