title: Web Audio API MediaElementSource node and SoundCloud not working with effects?
body: <p>I am using a SoundCloud URL as <code>audio.src</code> . It is only playing the unprocessed version when i run it through the delay chain i have.
  Here is the fiddle: 
  <a href="http://jsfiddle.net/ehsanziya/nwaH3/" rel="nofollow">http://jsfiddle.net/ehsanziya/nwaH3/</a></p>
  
  <pre><code>    var context = new webkitAudioContext();
      var audio = new Audio(); //creates a HTML5 Audio Element
  
      url = 'http://api.soundcloud.com/tracks/33925813/stream' + '?client_id=c625af85886c1a833e8fe3d740af753c';
      //wraps the soundcloud stream to an audio element.
      audio.src = url;
  
      var source = context.createMediaElementSource(audio);
      var input = context.createGainNode();
      var output = context.createGainNode();
      var fb = context.createGainNode();
      fb.gain.value = 0.4;
  
      var delay = context.createDelayNode();
      delay.delayTime.value = 0.5;
  
  
      //dry
      source.connect(input);
      input.connect(output);
  
      //wet
      input.connect(delay);
      delay.connect(fb);
      fb.connect(delay);
      delay.connect(output);
  
     source.mediaElement.play();
  </code></pre>
  
  <p>The chain works with Oscillator node.
  What is the reason for it?</p>
  
  <p>And is there any other way of processing a streaming sound from SoundCloud with Web Audio API?</p>
