title: SoundCloud stream request returning error on Safari iOS
body: <p>Getting the following error on Safari iOS (and since I can't get a song to play on Chrome, I'm assuming Chrome is having the same issue).</p>
  
  <pre><code>TypeError: 'null' is not an object (evaluating 'h._setVolume')
  line: 38

  <p>I'm getting the above error after running.</p>
  
  <pre><code>SC.stream('http://api.soundcloud.com/tracks/55499783/stream', function(stream) {
      stream.play();
  });
  </code></pre>
  
  <p>Is this a bug in SoundManager?  Am I missing something in the docs?  This exact same codebase works fine in any desktop browser.</p>
