title: Audio in html5 not working in FF4/Safari
body: <p>I got this audio link in my html5 document:</p>
  
  <pre><code>   &lt;audio 
        src="http://sverigesradio.se/topsy/ljudfil/3017771.m4a" 
        type="audio/mp4" 
        controls="true" 
        preload="metadata" 
        title="Senaste sändningen från Radiosporten"&gt;
     Senaste sändningen från Radiosporten&lt;/audio&gt;
  </code></pre>
  
  <p>It renders properly in chrome, but in FF4 it first flashes the controls normally and then I get a big "X". In safari, it seems to hang while reading metadata.</p>
  
  <p>Is there a problem with my audio-tag or with the audio-file? Is the redirect a problem?</p>
