Sorry for duplicate post. I was lost in mac land thread. I just bought a sony vaio (windows xp) and hooked up my Logitech Quickcam Fusion web cam. When the cam is plugged in there is no sound on my laptop at all. I-tunes won't play and I can't hear other people caming me. I can see them and they can see me. They can hear me but I can't hear them. I can hear others fine and hear I-Tunes as long as the camera is not plugged in. Any help or pointing in the right direction would be great!
