Safari 11 (and future versions of Chrome) prevent videos that have audio from autoplaying.

NOTE: Videos that are muted or set to Play on Touch will still autoplay as normal

  • This update automatically adds a play button when the browser stops autoplay.
  • There are a lot more options to set up your autoplaying videos which are all explained in the blog post here: https://www.bigwhiteduck.com/posts/sections-autoplay-videos
  • There is also an instructional video on best practices for setup and how to use external play/pause and mute buttons.
