Only one deck has audio output on DJay software, Windows

Hi there,

I recently downloaded DJay for windows and am using the Denon MC6000 mixer. For some reason, only Deck A works playing over my speakers. Deck B has all the controls operational and the song loads up fine and is ready to be mixed, but no sounds come out. I also have Traktor and no such problems occur on that software so I haven’t messed around with the Denon. Any advice on what to do?
