Hello and Good Day

I am having problems with a flash file i am working on. Basically i have created a slideshow/ebook that includes two buttons that move forward and backward on the timeline. On each page or frame of the main timeline are other buttons and movie clips.
Anyways, I am trying to figure out how ,for example , if the user flips forward quickly through the slideshow that the sounds do not continue to play on the next or previous frames. Everything else on the file works great , it's just a matter of keeping the sounds from overlapping.

I am new to action script and have searched hi and low for a solution.
If you have any ideas plz
