[flexcoders] Trying to make SoundManager class using getDefinitionByName

[Tracy Spratt]

I am trying to make a sound manager class that will simplify playing a sound by 
using an id string.  I have embedded the sound files, but am havign trouble 
getting the Sound object initialized. I get an error, "Variable beep1 is not 
defined" though cllearly it is.

I suspect I am misusing getDefinitionByName.  If there is an easier/better way, 
I am open to that as well.  The full class code is below.

package assets.sounds
{
  import flash.utils.getDefinitionByName;
  import flash.media.Sound;
  
  public class SoundManager
  {
    [Embed(source="beep-1.mp3")]private var beep1:Class;
    [Embed(source="beep-2.mp3")]private var beep2:Class;
    [Embed(source="beep-3.mp3")]private var beep3:Class;


    public function playSound(sSoundName:String):void
    {
      var classRef:Class = getDefinitionByName(sSoundName) as Class;  
//Variable beep1 is not defined.
      var s:Sound = new classRef as Sound;
      s.play();
    }//playSound
  }//class SoundManager
}//package assets.sounds
