Hi all, I use ventrillo a lot, and all of a sudden my microphone just stopped working. I went out and bought a new one, and it was fine for a week or two then that one stopped working. Bought another, worked for a few days now that one stopped working.I picked up a usb headset with microphone, when I plug it in, the computer recognises it as a usb headset, but the microphone just doesn't work. Anyone able to assist me?
