Sound card set up problems

OK here is my new problem. I can play music thru both channels of my analog mixer using my MIXVibe software players. I can not use the jog wheel on the software the control playback. My analog mixer and CD players are hooked up thru MAYA 44. When I try to use the jog wheel on my CD players I only get the test signal coming thru over top of the music playing from the MixVibes. CD 2 unit still plays thru channel 1 when I use my external CD players.
Please Help!
