title: mediaelement.js setSrc method not working
body: <p>I try using mediaelement.js..</p>
  
  <pre><code>var player = new MediaElementPlayer('#player',{
   startVolume:0.5,
   alwaysShowControls:true
  });
  </code></pre>
  
  <p>it's nice working when "src" is static. but with dynamic src </p>
  
  <pre><code>player.setSrc('link_to_audio');
  </code></pre>
  
  <p>browser returns error - <strong>TypeError: Object # has no method 'setSrc'</strong></p>
