Hello,
i am using a 5.1 Sound System, and an always plugged in USB Headset from Logitech with no Software. It's deactivated while i m gaming or watching a movie. When I activate it my Speakers automatical don't play any sound, just my headset. That's it for EVERY Application EXCEPT the WMP 9, it's annoying if you want to listen to music while being in TeamSpeak and it comes out the Speaker instead the Headset.
Know what i mean? Any ideas?
