title: <audio> src change with javascript
body: <p>I want to change the src attribute of a  tag using javascript and a button :</p>
  
  <pre><code>&lt;audio id="playme" src="" controls="controls"&gt;Your browser...&lt;/audio&gt;
  </code></pre>
  
  <p>And a little further down the page :</p>
  
  <pre><code>&lt;input type="button" style="font-size: 10px;"
          OnClick="document.getElementById('playme').src='snd/SOUND.WAV';"
          value="Listen"&gt;
  </code></pre>
  
  <p>It seems to just do nothing. Anyone has a clue ? Thanks a million</p>
  
  <p>Using Firefox 3.6 on Xubuntu 10.10</p>
  
  <p><strong>EDIT</strong> : it seems to work on Chrome but Firefox doesn't like it. Should I report a bug ? Do you know a way to bypass that ?</p>
