Following Chrome & Firefox\'s recent update autoplay videos are no longer supported - I\'ve tried to add some code to play this on startup but it doesn\'t seem to work?<
According to my own observations and many articles like this one for example, Chrome now blocks autoplay for videos unless they are muted. Videos with sound enabled can only be played by user interaction, e.g. a mouse click or a touch tap and cannot be started by javascript.
By doing this Google wants to "(make) auto-play more consistent with user expectations and [...] give users more control over audio" [1]
