autoplay videos on mute

Hi chaps,

We have vlogger theme and we have a small issue.

We can either autoplay videos on posts or single pages, but they will play with music, which can be annoying.

Right now, we have deactivated autoplay because of this reason, but what we want is a solution to autoplay on mute. Is this an option? if so, how?

Thanks
