Now, I finally got off my arse and bought an XBL headset (I've had my 360 for a while, but, the headset was faulty), and I seem to be having an issue with it. I have it plugged in, the switch halfway down the cord is set so that the green side is visible, but, when I play Halo 3, it displays a cancellation sign instead of the comm-tower looking icon. Please explain the problem if at all possible.
