Hey egouldmedia,
Thank you for the link to your site, most browsers are quiet strict about auto playing videos now, the audio must be disable and iPhones are the strictest and may block completely.
I created a test page linked below with your YouTube video in the LayerSlider with autoplay and “Play Muted” enabled and tested in Windows in Chrome, Firefox, Brave & Edge and on Android and it worked correctly. You can test on your device, but forcing workarounds are more limited these days.
The settings I used in the LayerSlider was the Video layer:
with your YouTube video link and no added attributes:
and then choose “autopaly after opening” and the “Play Muted” enabled:
please give this a try.
Best regards,
Mike
