WCAG 1.4.2 Audio Control
Level A
If audio plays automatically for more than 3 seconds, give the user a way to pause, stop, or control its volume independently of the system volume.
Common failures
- Background video autoplays with sound and no on-page mute control.
- Background music loops with no UI to silence it.
How to fix
- Don't autoplay audio. If you must, expose an obvious mute/stop control.
- Mute autoplaying media by default and require user gesture to unmute.
