Web banner + sound clip

hey guys, I hope someone can help with this:

I’ve made a web banner that animates on the main timeline.
I’ve added a sound clip (it’s about 45 secs long).

Works well, but I would like to have the sound clip play only once. The way it is right now, everytime the movie loops so does the sound clip. I’ve tried setting the mp3’s repeat property to zero, but it still plays.

Is it better in this case to use “linkage”, probably, but can someone explain how I would set this up please, the actionscript etc :slight_smile:

Thanks
