title: How to mute embeded youtube video? Volume = 0 doesn't work
body: <p><br>
   <strong>volume=0</strong> doesn't seem to be supported anymore. <br>
  Does anyone know how i can mute my iframe now in year of 2017?</p>
  
  <p>When i click unmute icon, mute icon should appear and video should be muted. (and the other way around) <br><br>
  <strong>This is what iv tried thus far:</strong></p>
  
  <pre><code>//Mute-Unmute Music
   $('#unmute').on('click', function() {
      $("#unmute").hide();
      $("#mute").show();
      $("#iframe").attr("volume", "0");
   });
   $('#mute').on('click', function() {
      $("#mute").hide();
      $("#unmute").show();
      $("#iframe").attr("volume", "1");
    });
  </code></pre>
