Hi,

I’m using external swf in a project, and I got one swf with startup audio play, I can’t stop the sound to play when I load another swf via this code :

```auto

            clearButtons();
            TweenLite.to(m.target, 0.5, {tint:0xcc0000});
            m.target.mouseEnabled = false;
            m.target.mouseChildren = false;
            m.target.buttonMode = false;
            m.target.removeEventListener(MouseEvent.MOUSE_OVER, functionOver);
            m.target.removeEventListener(MouseEvent.MOUSE_OUT, functionOut);
            id=m.target.id;            
            loader.unload();
            globalContainer.removeChild(loader);
            rimuoviListeners(loader.contentLoaderInfo);
            caricaSezione(id);

```

I’ve tested loader=null but I get errors, i’m using external document class to manage all this.  
many many thanks for your help.

Matt
