[html] YouTube: How to present embed video with sound muted

I'm trying to embed a video with the sound muted but I can not figure out how it make it work.

Currently I'm using this but doesn't work:

<iframe src="https://www.youtube.com/embed/uNRGWVJ10gQ?rel=0&amp;autoplay=1" width="560" height="315" frameborder="0" allowfullscreen></iframe>

Any of you knows how can I make this work ?

   <div id="player"></div>
    <script>

          var tag = document.createElement('script');
          tag.src = "https://www.youtube.com/iframe_api";
          var firstScriptTag = document.getElementsByTagName('script')[0];
          firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);

          var player;
          function onYouTubeIframeAPIReady() {
            player = new YT.Player('player', {
              height: '720',
              width: '1280',
              videoId: 'M7lc1UVf-VE',
              playerVars :{'autoplay':1,'loop':1,'playlist':'M7lc1UVf-VE','vq':'hd720'},
              events: {
                'onReady': onPlayerReady,
                'onStateChange': onPlayerStateChange
              }
            });
          }

          function onPlayerReady(event) {
               event.target.setVolume(0);
           event.target.playVideo();
          }

          var done = false;
          function onPlayerStateChange(event) {
            if (event.data == YT.PlayerState.PLAYING && !done) {
        //      setTimeout(stopVideo, 6000);
                      done = true;
            }
               event.target.setVolume(0);
          }
    </script>

was also looking for a solution to this but I wasn't including via iframe, mine was linked to images/video.mp4 - found this https://www.w3schools.com/tags/att_video_muted.asp - and I simply added < video controls muted > (CSS/HTML 5 solution), but no JS required for me...

The accepted answer was not working for me, I followed this tutorial instead with success.

Basically:

<div id="muteYouTubeVideoPlayer"></div>
<script async src="https://www.youtube.com/iframe_api"></script>
<script>
 function onYouTubeIframeAPIReady() {
  var player;
  player = new YT.Player('muteYouTubeVideoPlayer', {
    videoId: 'YOUR_VIDEO_ID', // YouTube Video ID
    width: 560,               // Player width (in px)
    height: 316,              // Player height (in px)
    playerVars: {
      autoplay: 1,        // Auto-play the video on load
      controls: 1,        // Show pause/play buttons in player
      showinfo: 0,        // Hide the video title
      modestbranding: 1,  // Hide the Youtube Logo
      loop: 1,            // Run the video in a loop
      fs: 0,              // Hide the full screen button
      cc_load_policy: 0, // Hide closed captions
      iv_load_policy: 3,  // Hide the Video Annotations
      autohide: 0         // Hide video controls when playing
    },
    events: {
      onReady: function(e) {
        e.target.mute();
      }
    }
  });
 }

</script>

Try this

<iframe width="420" height="315" src="http://www.youtube.com/embed/
HeQ39bLsoTI?autoplay=1&cc_load_policy=1" volume="0" frameborder="0"
allowfullscreen></iframe>

don't forget to write volume="0"

For me works using &autoplay=1&mute=1

I would like to thank the friend who posted the codes below in this area. I finally solved a problem that I had to deal with all day long.

This is easy. Just add mute=1 to the src parameter of iframe.

Example:

<iframe src="https://www.youtube.com/embed/uNRGWVJ10gQ?controls=0&mute=1&showinfo=0&rel=0&autoplay=1&loop=1&playlist=uNRGWVJ10gQ" frameborder="0" allowfullscreen></iframe>

<iframe  src="https://www.youtube.com/embed/7cjVj1ZyzyE?autoplay=1&loop=1&playlist=7cjVj1ZyzyE&mute=1" frameborder="0"  allowfullscreen></iframe>

mute=1

Just pass mute=1.

For example:

<iframe id="myVideo" src="https://www.youtube.com/embed/k0DN-BZrM4o?rel=0&amp;autoplay=1;mute=1" width="100%" height="600" frameborder="0" allowfullscreen></iframe>
