title: HTML5 audio control greyed out when playing from external hard drive
body: <p>Im trying to play mp3 files from an external hard drive connected to raspberry pi on web browser (webserver is the raspberry pi). My code is so far simply to test.</p>
  
  <pre><code> &lt;!DOCTYPE html&gt;
  &lt;html&gt;
  &lt;body&gt;
      &lt;audio controls&gt;
          &lt;source src="kyon.mp3" type="audio/mp3"&gt;
      &lt;/audio&gt;
    &lt;p&gt; &lt;audio controls&gt;
          &lt;source src="shakira.mp3" type="audio/mp3"&gt;
      &lt;/audio&gt;
    &lt;p&gt; &lt;audio controls&gt;
        &lt;source src="/mnt/SEAGATE_BACKUP_1/MP3/Carly_I_Really_Like_You.mp3" type="audio/mp3"&gt;
          &lt;/audio&gt;
      &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>I can play first two mp3 but cannot play the third, I have checked permissions which seem fine.</p>
  
  <p>Any idea?</p>
