Cant Autoplay

I am unable to get the video playlist to autoplay.

This feature used to work perfectly and has suddenly stopped working with no changes made to the site.

I have tried a variety of different shortcode varieties, currently this is the current value:

[youlist uid=”TVEUReporter” autoplay=”1″ width=”920″ height=”540″ listtype=”user_uploads” showinfo=”1″]
