oh if you can do the second suggestion.. it’s easy to do the third one ??
setTimeout(autoPlayVideo, 5000);
function autoPlayVideo() {
var videoframe = document.getElementById('videoframe');
videoframe.src = videoframe.src + '?autoplay=1';
}
this will add delay to the youtube video with iframe id=”videoframe”
and for the sound: maybe this will help you ?
