Flash AS3 Event.SOUND_COMPLETE

Har lavet en simpel audio player i flash.
(kildekode i bunden)

mit problem er at min Event.SOUND_COMPLETE aldrig bliver "fanget"

nogen forslag til hvad jeg har gjort forkert?
*************
Kildekode:
import flash.events.Event;
import flash.events.ProgressEvent;
import flash.media.Sound;
import flash.net.URLRequest;
import flash.media.ID3Info;

var s:Sound = new Sound();
s.addEventListener(ProgressEvent.PROGRESS, onLoadProgress);
s.addEventListener(Event.COMPLETE, onLoadComplete);
s.addEventListener(IOErrorEvent.IO_ERROR, onIOError);

var id:int = 1;
var req:URLRequest = new URLRequest(id+".mp3");
s.load(req);
var channel:SoundChannel;
var localSound:Sound;
function onLoadProgress(event:ProgressEvent):void
{
    var loadedPct:uint =        Math.round(100 * (event.bytesLoaded / event.bytesTotal));
    trace ("The sound is " + loadedPct + "% loaded.");
    songText.text = loadedPct + "% loaded.";
}

function onLoadComplete(event:Event):void
{
  localSound = event.target as Sound;
  channel = localSound.play();
  channel.stop();
 
  songText.text  = s.id3.songName + " - " + s.id3.artist;
}
function onIOError(event:IOErrorEvent)
{
    songText.text = "The sound could not be loaded";
    trace("The sound could not be loaded: " + event.text);
}

//----- virker ikke!!!!!--------------

s.addEventListener(Event.SOUND_COMPLETE, onPlaybackComplete);
function onPlaybackComplete(event:Event)
{
    songText.text = "The sound has finished";
    trace("The sound has finished playing.");

}

var pausePosition:int = 0;
btnPlay.addEventListener(MouseEvent.CLICK,btnPlayClickHandler);
function btnPlayClickHandler(Event:MouseEvent):void{
    channel = localSound.play(pausePosition);

}

btnPause.addEventListener(MouseEvent.CLICK,btnPauseClickHandler);
function btnPauseClickHandler(Event:MouseEvent):void{
    pausePosition = channel.position;
    channel.stop();
    btnPlay.visible = true;
}

btnNext.addEventListener(MouseEvent.CLICK, nextSong);
function nextSong(event:MouseEvent):void {
    pausePosition = 0;
    if (id == 4)
    {
        id = 0
    }
    id++;
    channel.stop();
    trace(id);
