ok. SO. i have the Win 7 running my M-Audio Fast Track Ultra sound card. Traktor Pro 2.5.1 is running smooth. but now a new issue. and its all about Cueing tracks through headphones. sound is coming through my monitors, same with the headphones (plugged into sound card) and the controller (VCI-100 mk2) is working. but when i hit the cue button on the Vestax, nothing comes through on the headphones. just.. dead. here are some set up pix. i feel i have tried so many options, any help would be greatly appreciated
