title: Cannot Switch HTML5 Audio SRC
body: <p>All,
  I have a web app that streams audio in html5/javascript/css
  When I start it and select a stream, that stream plays as expected.
  When I attempt to switch from that stream to another url, the program gets to the point where the new url is bufferred, but nothing plays. I don't hear anything. Any idea what may be going on here? 
  This behavior occurs on the actual smartphone device. It does not occur when I run the program in Chrome.
  Here's my code:</p>
  
  <pre><code>//global audio variable here
  var audio = new Audio;
  audio.setAttribute("autoplay","autoplay");
  //Then within an function in the same jscipt file, I set the url. It's                  
  //when this runs a second time with a different url that it stalls.
  audio.pause();
  audio.setAttribute("src", "");
  audio.setAttribute("src", result.rows.item(q).url_);
  audio.load();
  </code></pre>
