Autoplay guide for media and Web Audio APIs - Web media technologies
rowsers often provide various forms of autoplay blocking. in this guide, we'll cover autoplay functionality in the various media and web audio apis, including a brief overview of how to use autoplay and how to work with browsers to handle autoplay blocking gracefully. autoplay blocking is not applied to <video> elements when the source media does not have an audio track, or if the audio track is muted. media with an active audio track are considered to be audible, and autoplay blocking applies to them. inaudible media are not affected by autoplay blocking. autoplay and autoplay blocking the term autoplay refers to any feature that causes audio to begin to play without the user specifically requesting that playback begin. this includes both the use of html attributes to autoplay media as well...
