Ok sorry i have to crash into this forum with a question off the bat but the traktor forums are really miserable to get any help.

I picked up dj'ing and went for the traktor S2 to start out.
I installed traktor pro and hooked everything up to my computer, but i have a problem getting sound from traktor.
I have several audio devices to choose from, my 2 headsets, my little 2.1 desktop speakers and i also have my computer connected with a HDMI cable to my receiver so i can watch stuff playing on my pc on my actual tv behind me. When i play music i actually choose my tv as audio device in windows. This way the sound runs through my HDMI cable to my receiver to my 5.1 surround system wich btw just plays stereo when playing music. Im not trying to dj with 5.1 surround audio but whatever, that's not the point. The problem is that traktor doesn't recognize my hdmi as an audi device so i cannot get it to work with my receiver. How do i fix this?

Grtz
