Reply to Need help with setup!

I am trying to connect my CDJ 100s to connect with traktor on my macbook, however I can't get any sound to come through the speakers from traktor.

I am using:
Macbook pro
2 x Pioneer CDJ100s
1 x Pioneer DJM 300s mixer
Traktor 2 Soundcard
I also use a Cambridge Audio Topaz AM5 amp, and 2x Aviano 1 speakers.

Sound is successfully coming through my CDJs to speakers, but I can't get what is happenning on my decks to the visuals on traktor? Do I have to sync/calibrate something? I've tried playing tracks through traktor straight into my speakers and the sound works fine.

I'm a total novice when it comes to setting up things like this, to the point where I don't know if I've just wired this wrong.
Are you able to somehow help me with my setup?
Any help is much appreciated.
