My speaker set up was working just fine, before I unplugged it.
I run windows 7, i7950.
I have a subwoofer, and 5 speakers - one of the old logitec systems, and I have a steelseries headset/mic.
I change the default option, when i want to move from speakers and to mic/headset.
The speakers were set to :asus xoner DG audio device.
The headset was : speakers realtec HD audio.
Now both options just play sound from my headset.... I have unplayed the speakers...replugged them.....nothing works.
