I did this with XP. But can't seem to do it with Windows 7... Basically, I want Media Center to run thru the speakers and at the same time, I would like Windows Media Player to run thru the headset. This was possible on XP and Vista. It actually did it automatically. I can have media center on running Live TV and open up a Mp3 on WMP. Then hook up my USB headset and the WMP would automatically play on the headset and Live tv will still run thru the speakers.. When I try to do this on Win7 x64, the speaker shuts off and all sound goes thru the headset once I connect it. It is possible to do this on win7?
