I can hear both Deck when the Crossfader is only on one!

hey there i am using CrossDJ 2.0.1 with U-Mix Control Pro. Also i have the Xonar D2x Soundcard if this helps

I have got the controller plugged into the line in on my new sound card and for some reason i hear Player B whilst the crossfader is over on A but when im over on B i dont get anything from A which is how it should be.

You are using the outputs of the U-Mix Control Pro so this is where the sound is coming from, not your 5.1 not the other one
