Friggin thing was driving me nuts.. Couldn't hear a thing I was saying in testing playback. anyway after like 2 hours of messing with things I finally tried the obvious thing.. you know.. the thing I should of tried first.. XD.. disabling the usb headset in device manager. thats in control panel/system/hardware. then rebooting and re-enabling the device.. my usb headset sound is good to go.. for now.. might be only temporary.. but it fixed the problem.. Thought I'd post this just because I see topics all over the place where people can't figure out why their headset is going nutz.. something to try.. EDIT: yea it worked.. for a little while.. what a garbage mobo this is.. 680i sli total failure..
