Removing event listener for external audio tracks?

programming flash

I have a site that has many pages, and almost everypage has an external audio track that is brought in using actionscript. (Creating an audio channel)


var isPlaying:Boolean = new Boolean();var pausePosition:Number = new Number();




//Create an instance of the Sound class
var daynaClip1:Sound=new Sound();


//Create a new SoundChannel Object
var d1Channel:SoundChannel=new SoundChannel();


//Load sound using URLRequest
daynaClip1.load(new URLRequest("audio/slide2_narrator.mp3"));


//Create an event listener that wll update once sound has finished loading
daynaClip1.addEventListener(Event.COMPLETE,onComplete,false,0,true);


function onComplete(evt:Event):void {
    //Play loaded sound
    d1Channel=daynaClip1.play();
	isPlaying = true;
	
}

This works perfectly, the sound starts playing and all.

The Problem…
However it seems that sometimes on the site, when it is on the webserver, and not when it is playing back locally, some of these audio tracks will either continue playing after you leave the page, or sometimes, many of them will start playing at the same time on a page where they should not be playing at all. I cannot figure out what would cause this.

My guess is I need to disable the eventlistener, so that after you leave the page, they can’t trigger again until you come back to the page? But I do not know how to remove the event listener.

Is my assumption right? If so, how do I implement this? And if my assumption is wrong, does anyone have any suggestions of what to do to stop the audio from mysteriously playing where it shouldn’t be playing?
