Traktor Problem

Hey guys! Here i leave you a problem i have with my traktor gear. I have changed the cables, the latency, the sample rate an some things in transport settings, and the problem seems to vanish, but then it appears again. i hear like a "crush sound like effect" on the beat but then it gets louder until i hear nothing exceptt that annoying sound. i dont know what it is but i think it is my Traktor Audio 6 soundcard Interface. HELP PLEASE!!
