Softimage Xsi: Audio Scrubbing ???

Hey all. This may make me sound like a newb but I cant get my audio clip to scrub or even work at all. I draged a .wav file into my scene and put the clip into the animation mixer then scrubbed through it and I occasionaly get a noise but it seems completely random when / if they happen. I made sure I had the "play audio when scrubbing" on in the user preferences but after that I dont even know where to start looking.


any insight would be great. Thanks,
