Traktor pro 2 static only

Hey guys, im using my cdj-900s and xone 42 with traktor pro 2. Everything was working fine and randomly everything stopped working properly. I have the lasted drivers for my cdj-900s and am updated to the latest traktor pro 2. I set the audio hardware to cdj asio and set my outputs to cdj 900 1 L/R for output A and cdj 900 2 L/R for output B.

Now everything gets controlled no problem, but only one cdj actually outputs music where as the other cdj does nothing but static, loud annoying static. What can be causing this?

Thanks

Have you tried a different audio/usb cables? Do both CDJs work normally outside Traktor or work fine if only one is plugged?

Yes I tried different cables, and both cdj-900s work perfectly with a USB drive not connected to the computer.
