Open up your JS folder (onetone/js), you will find a file called jquery.tabular.1.0.js.
Open this up in any text editor. Find this block:
// defaults
var defaults = {
ratio: 16/9, // usually either 4/3 or 16/9 — tweak as needed
videoId: ‘ZCAnLxRvNNc’, // toy robot in space is a good default, no?
mute: true,
repeat: true,
width: $(window).width(),
wrapperZIndex: 99,
playButtonClass: ‘tubular-play’,
pauseButtonClass: ‘tubular-pause’,
muteButtonClass: ‘tubular-mute’,
volumeUpClass: ‘tubular-volume-up’,
volumeDownClass: ‘tubular-volume-down’,
increaseVolumeBy: 10,
start: 0,
container:”body”
};
then change mute from true to false, like this: mute: false,
