I am trying to play the background video music as soon as the site opens up. I have injected the following code in both the footer and header. On the edit site in squaresace it will show the video auto playing with the sound as well just how i want it. However, when I visit the actual site the video disappears. Can someone help please? 

<!-- Plugin Background Video Controls -->
<link href="/s/plugin-background-video-controls.css" rel="stylesheet">
<script src="/s/plugin-background-video-controls.js"></script>
<script>pluginBackgroundVideoControls({"unmute":"true"});</script>
<!-- end Plugin Background Video Controls -->

It shows fine to me. Chrome/Windows
