Applicability

This rule applies to any audio or video element for which all the following are true:

  • autoplay: the element has an autoplay attribute value of true; and
  • not muted: the element has a muted attribute value of false; and
  • not paused: the element has a paused attribute value of false; and
  • duration: the element has a media resource lasting more than 3 seconds that contains audio.

Expectation

For each test target the total audio output does not last more than 3 seconds.

Note: This rule does not cover single audio instances that play repeatedly for more than three seconds, or multiple audio instances for more than three seconds. The WCAG Understanding documentation for 1.4.2 Audio Controls is ambiguous about how to handle these scenarios.
