No i dont want to unplug my main speakers from the rear port of my realtech soundcard. I want to be able to play lets say a show from my computer thats being sent to my tv...the tv is hooked up to the main outs on the soundcard. I then want to play the sound of sins out of my usb headset. i do this with wow, starcraft, world in conflict, crysis...ect. Is this possible?

By the way thanks. 

Thanks but thats not what i had in mind....Most games i have played allow you to change the audio output in the sound settings page....however sins doesnt have that option...I just wanted to make sure there wasnt another way to change the audio output from within the game. So that i can play the game and send audio and video to my tv so my girl can watch while i play.

Thanks again for the help though.
