title: as3 load, play and mute external swf
body: <p>I have a file to which I do not have the source - a flash header with an obnoxious sound intro and I need to mute all sounds. Without the source I am limited as to what I can do. I have some as3 code that I am using to try and load the swf into and mute(building in FlashDevelop). Here is the code in question:</p>
  
  <pre><code>package 
  {
  import flash.display.MovieClip;
  import flash.display.Sprite;
  import flash.events.Event;
  import flash.media.SoundTransform;
  import flash.net.URLRequest;
  import flash.display.Loader;
  import flash.media.SoundTransform;
  
  public class Main extends Sprite 
  {
      private var mLoader:Loader;
      private var mc1:MovieClip;
      private var holder:Sprite;
      private var mSound:SoundTransform;
  
      public function Main():void 
      {
          if (stage) init();
          else addEventListener(Event.ADDED_TO_STAGE, init);
      }
  
      private function init(e:Event = null):void 
      {
          var mRequest:URLRequest = new URLRequest('header_v8.swf');
          mLoader = new Loader();
          mLoader.load(mRequest);
          holder = new Sprite();
          holder.addChild(mLoader);
          addChild(holder);
          mSound = new SoundTransform(0);
          holder.soundTransform = mSound;
  
      }
  
  }
  </code></pre>
  
  <p>}</p>
  
  <p>This code above still plays the audio and the original swf is not being displayed. So, my questions are:</p>
  
  <p>How would I mute the external audio?
  How would I display the external swf just as it does when viewing it directly?</p>
  
  <p>Any suggestions or pointers to useful examples/documentation would be greatly appreciated </p>
