title: How do I automatically play a Youtube video (IFrame API) muted?
body: <pre><code>&lt;iframe class="youtube-player" type="text/html" src="http://www.youtube.com/embed/JW5meKfy3fY?wmode=opaque&amp;autohide=1&amp;autoplay=1&amp;volume=0&amp;vol=0&amp;mute=1" frameborder="0"&gt;&amp;lt;br /&amp;gt;&lt;/iframe&gt;
  </code></pre>
  
  <p>The video isn't muted! I want volume to be 0 when it first plays...</p>
