Little help with sound playback

Hi all,

I’m making this educational movie. It’s basically a PPT presentation with all the individual slides grabbed into jpegs and converted to a Flash movie (with forward/back arrows for users to navigation in a non-linear way).

On each slide there is a short narration about the current slide.

My problem…
When the user clicks forward or backwards, the current sound file doesn’t stop. I need it to stop because the narration for the new slide will start automatically and overlap with the narration that is playing.

I tried using Sound.stop on every frame but it doesn’t work!

Thanks a lot for viewing! :beam:
