title: Audio not working in html5
body: <p>I was adding audio to an HTML5 website. The audio works fine with FireFox and IE but does not show up and play in FireFox. Any ideas why and solution? Thanks in advance.</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;!DOCTYPE HTML&gt;
  &lt;html&gt;
  &lt;head&gt;
  &lt;meta http-equiv="Content-Type" content="text/html; charset=utf-8"&gt;
  &lt;title&gt;Untitled Document&lt;/title&gt;
  &lt;/head&gt;
  
  &lt;body&gt;
  &lt;audio controls="controls" autoplay="autoplay"&gt;
   &lt;source src="cd.mp3" type="audio/mpeg" /&gt;
   Your browser does not support the audio element.
  &lt;/audio&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
