Reply to Another VCI-100 question...

Ok I have a VCI-100, a Macbook Pro, a M-audio Fast track Pro, Sony tuner and Infinity home speakers. I am using Traktor LE for now. I need help setting up sound in Traktor LE. When I play music, both tracks come through both speakers and all of the connections are in the right place. What am I missing, I know I am probably setting up Traktor wrong...
