Loop sound in each background

Question

Someone helped me last time with my sounds. Now, when my player enters in a scene, a new sound starts (and the sound of the previous background stops).

But now I can't find a way to loop the sound in each background...I'm trying to use

public function playSound():void{
            channel = music.play();
            channel.soundTransform = transformer;
            channel.addEventListener(Event.SOUND_COMPLETE, loopSound, false, 0, true);
            }
            private function loopSound(e:Event):void{
                channel.removeEventListener(Event.SOUND_COMPLETE, loopSound);
                playSound();
            }

But it doesn't seem to work. In fact, I don't really know when should I call this function.

I've got a quite simple code :

  public var currentSoundChannel:SoundChannel;
    public function newBackground(thisBack:String):void
    {
        var room = back.currentBack;
        if (currentSoundChannel != null)
        {
            currentSoundChannel.stop()
        }
        var nextSong:Sound;
        switch (thisBack){
            case "maisonExt":
                nextSong = new exterieur ();
                break;
            case "garage":
                nextSong = new mouche ();
                break;
            case "monde":
                nextSong = new cartesnd();
                break;
        }
        currentSoundChannel = nextSong.play();
    }

So, where should I put my loopsound function ?

Thank you very much !

Normaly I use a class for the background music named "musique.as". Here's the code :

public function Muzak(musicURL:String, musicVol:Number){
                                               this.musicURL = musicURL;
                                               if(musicURL != ""){
                                                               music = new Sound(new URLRequest(musicURL));
                                                               transformer  = new SoundTransform(musicVol, 0);
                                                               playSound();
                                               }
                               }
                               public function playSound():void{
                                               channel = music.play(0,100);
                                               channel.soundTransform = transformer;
                                               channel.addEventListener(Event.SOUND_COMPLETE, loopSound, false, 0, true);
                               }
                               private function loopSound(e:Event):void{
                                               channel.removeEventListener(Event.SOUND_COMPLETE, loopSound);
                                               playSound();
                               }
                               public function changeVolume(newVol:Number):void{
                                               if(musicURL != ""){
                                                               transformer.volume = newVol;
                                                               channel.soundTransform = transformer;
                                               }
                               }
                               public function stopSound():void{
                                               channel.stop();
                               }

But as I wanted to change the music in each background so I add in my Engine class :

public var currentSoundChannel:SoundChannel;         
public function newBackground(thisBack:String):void     {         
var room = back.currentBack;        
 if (currentSoundChannel != null)        
 {            
 currentSoundChannel.stop()       
  }      
   var nextSong:Sound;
.....
 nextSong = new "mysoundname"();
....
}         currentSoundChannel = nextSong.play();

use:

public function Muzak(musicURL:String, musicVol:Number){
                                               this.musicURL = musicURL;
                                               if(musicURL != ""){
                                                               music = new Sound(new URLRequest(musicURL));
                                                               transformer  = new SoundTransform(musicVol, 0);
                                                               playSound();
                                               }
                               }
 
                               public function playSound():void{
                                               channel = music.play(0,100);
                                               channel.soundTransform = transformer;
                                              // channel.addEventListener(Event.SOUND_COMPLETE, loopSound, false, 0, true);
                               }
 
                               private function loopSound(e:Event):void{
                                               channel.removeEventListener(Event.SOUND_COMPLETE, loopSound);
                                               playSound();
                               }
 
                               public function changeVolume(newVol:Number):void{
                                               if(musicURL != ""){
                                                               transformer.volume = newVol;
                                                               channel.soundTransform = transformer;
                                               }
                               }
 
                               public function stopSound():void{
                                               channel.stop();
                               }

or

public var currentSoundChannel:SoundChannel;         
public function newBackground(thisBack:String):void     {         
var room = back.currentBack;        
 if (currentSoundChannel != null)        
 {            
 currentSoundChannel.stop()       
  }      
   var nextSong:Sound;
.....
 nextSong = new "mysoundname"();
....
}         currentSoundChannel = nextSong.play(0,100);

And I should put "channel = music.play(0,100); // 100 loops" where exactly in order to have a loop sound in each background ?
