Play sound on frame event!

Hi guys,

I’m putting music for my flash website, I’m adding the audio using Actionscript as per the tutorial below:

This is my script assigned to a mc at the frame I want the music to start play:

onClipEvent (load) {
mySound = new Sound();
mySound.setVolume(_root.volume*2);
mySound.attachSound(“backgroundmusic”);
mySound.start(0,999);
}

with a stop(); on that frame.

the problem is that obviously flash keeps creating that sound over and over on top creating a chaos!

Is there anyway to trigger that sound only once!?
or how can I trigger it when it reaches a certain frame without using a clipEvent?

Please help since that the only thing keeping me from launching the website! :hurt:

thx.
