title: HTML5 audio tag bug in Firefox
body: <p>I'm building a website with a music player, using an <code>&lt;audio&gt;</code> tag.</p>
  
  <p>I'm using jQuery to make some basic operation like "pause" and "play":</p>
  
  <pre><code>$("#music_player")[0].pause();
  
  $("#music_player")[0].play();
  </code></pre>
  
  <p>In Chrome everything seems to be fine, but in Firefox it isn't working.</p>
  
  <p>Does somebody know what is the problem? Or what other commands in JavaScript can control the audio tag?</p>
