Traktor 2.6, CDJ 900 - Audio through 1 Channel only?

I have a slight issue, in that, the audio from both of my decks when connected to Traktor is coming out of 1 channel on the mixer (decks and mixer are connected up right as when using CD's the audio comes through channels 1&2). I believe it is an output rooter problem within Traktor (or laptop?) but I am not given the option when in settings in Traktor to solve this. All firewire and drivers and software is updated to the latest versions.

Anyone else had this issue?

What interface are you using?
Can you post a screenshot of your output routing

 

I assume you have it setup for external mixing.

 

Make sure that you do not have either the aggregated CDJ or an individual CDJ selected as your main audio device in Windows or OSX, as this will interfere with the CDJ Asio drivers.

Assuming you have successfully created an aggregate audio device with your two decks of course.

 

I have taken these two snap shots showing that there isn't much of an option!
Please see attachments.

 

I assume I have but then it's not working properly so I might have not got it right?

I have created the aggregate audio with the 2 decks and made sure that I didn't use the CDJ as the main audio in 'Sound' in System Preferences but was only given the choice of internal speakers or CDJ's. Could this be the problem?

 

Problem sorted - thanks for all the advice!
