I hope you are well today and thank you for your question.
When I visite your website on the desktop then also the video is muted as shown in the attached screenshot.
How are you using the video on your website?
Which mobile and browser are you using?
Well, regardless, we don’t want it muted on either desktop or mobile… You can see in the source that it isn’t muted, but loads muted? The embedded video further down the page works as expected.
How can we get the revslider video layer to play with volume as settings specify?
I can see the video is allowed to autoplay and as described in the below page all videos that are set to autoplay will be muted automatically due to new browser restrictions.
So to resolve the issue, please try disabling the video autoplay.
