Safari on macOS
Safari 11 on macOS and iOS, as well as Chrome for Desktop and Mobile are going to introduce a new auto-play policy. The main goal is to improve their user’s browsing experience, by eliminating distractions and surprising media playbacks of unmuted content, and provide them with more control over the autoplay capabilities for individual websites. Additional options are available in the respective website preferences pane to allow or disable autoplay, disable audio in general or more. In addition to that, both browsers are going to introduce an automated approach, which decides if auto-play will be blocked for media elements with sound in general or if auto-play is disabled at all.
