Progress bar and linkage

Hi
I’ve just added a preloader to my project on frame 1 of the root. I’ve used this preloader before where all of my library items that are set to export for actionscript, I’ve unchecked the export in first frame box. I’ve then placed an instance of the symbols on frame 2 after the preloader. When the everything is loaded the preloader sends us to frame 3 where things begin. All of my mc symbols that are exported for actionscript work fine but not the audio. The audio worked before I put in the preloader and unchecked export in the first frame. Here’s the preloader code:

onEnterFrame = function() {
   var percentLoaded:Number = // wraps to next line:
       Math.floor(getBytesLoaded()/getBytesTotal()*100);
   if (percentLoaded == 100) {
      // clean up:
      delete(onEnterFrame);
      // jump over our asset frame, and
      // straight to our content frame:
      gotoAndPlay('intro');
    } else {
      loadStatus.text = "Loading: "+percentLoaded+"% done";
	  setProperty(loading_bar, _xscale, percentLoaded);
    }
}
stop();

Here’s how the audio is brought in.

var exampleSound:Sound = new Sound();
exampleSound.attachSound('example1Audio');
exampleSound.start();

any ideas?
