browsers don’t allow autoplay of sound-enabled videos

My issue come when I uploaded an mp4 video, the the sound option is set on “enable” and the browser does not let the videos to autoplay and what I see ist just a black screen.
The answer from the author is basically that that “browsers don’t allow autoplay of sound-enabled videos”

Is there any workaround?
I have tried to write again in the last weeks in the forum but no answer!

The workaround is to print a text that the user needs to allow the auto play/sound video. Otherwise, there’s no workaround. ( some browsers with some additional code it may be possible but not for all browsers )
