title: mp3 audio works in all browsers but not IE9
body: <p>I have three mp3 audio files that play fine in all browsers but play for only 1.x seconds in IE9 unless I change "controls" to "autoplay" in which case it plays just fine. </p>
  
  <p>I was then sent the original, unedited file in .wav format. I encoded it myself to mp3 but have the same problem. </p>
  
  <p>However, if I create my own mp3 audio file and insert it into the same markup, it works in all browsers, including IE9 with the "controls" attribute.</p>
  
  <p>I can only think there is something about the settings in the original audio file that would cause the issue but don't have a clue what that could be.</p>
  
  <p>Here is the test markup:</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
  &lt;head&gt;
  &lt;meta charset="utf-8"&gt;
  &lt;title&gt;&lt;/title&gt; 
  &lt;/head&gt;
  &lt;body&gt;
  &lt;audio src="poem.mp3" controls &gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>EDIT: </p>
  
  <p>I put three audio files on the page. Sometimes one or two will play all the way through while the third won't play at all. Other times, two will play for a second but the third does nothing.</p>
