Rollover + sound

Hi, I have a question about adding a sound to a rollover event.

I have a movie clip(middle) that has a rollover event on it to cue a button(blob) but I want a sound effect to play when the rollover happens. Is there a way to do this using actionscript? Any help would be appreciated, and sorry if this is a dumb question!

I’m using this code:

blob._visible=false;

middle.onRollOver=function(){
blob._visible=true;

}

if using flash cs3 - add the sound file to your library, give it a linkage - Actionscript class name. I’ve loaded the ding.wav, and linked it as a class called dinger.

var sndOver:Sound = new dinger();

sndOver.play();
