Reply to Traktor Sound Cuts Out

Hey everyone,

I have an s2 running Traktor. Sometimes the sound just stops all of a sudden on Traktor and I can't get sound back without closing the program and restarting it. It's weird because I can still move all the sliders like volume, pitch, crossfader, and eq's and also load tracks but I can't play anything at all. This is a big problem any help would be appreciated. Thanks in advance
