revolution slider automatic video play

Hi,
Since I updated operating system on my mac to macOS High Sierra the video has stoped playing automatically on my website with Highend theme.Apple has done an update on Safari browser which stops videos to play automatically.My understanding was it’ll be for a video with a sound.Although my video is only short clip with no sound that plays in the loop a bit like on your Highend template page, except the macOS update hasn’t affected the autoplay of your video that still plays in the loop on your website.
I wonder if you have a suggestion how to go around solving this problem?
Thanks
