I am using the wireless Microsoft XBox 360 controller with my computer to play madden 2008. I am also using the Logitech Z-Cinema speakers. When I plug the controller in, all the audio goes hazy and scratchy. Even if I unplug the controller, the audio stays the same until I restart my computer. I am wondering if there is any way to fix this, or if I should just give up the madden on the computer and get an XBox. If I do do that, would I be able to have the speakers and my monitor plugged into both my computer and the Xbox?
