Autoplaying Hero Video With Sound and No Pause Button
1.4.2 — Audio Control
Scenario
Setting
A video-conferencing app's meeting controls
What’s wrong
Auto-playing hero/ambient video with an audio track (not muted) and no visible pause.
Example
<audio src="intro.mp3" autoplay></audio>Why it matters
Screen-reader users competing with page audio, and people with auditory sensitivity.
How to test
Load the page: if a hero/ambient video with an unmuted audio track autoplays and there's no visible pause button, it fails.
How to fix
Audio must not autoplay beyond 3 seconds without an obvious, keyboard-usable pause/stop/volume control.
<audio src="intro.mp3" autoplay controls></audio>Autoplaying audio past 3 seconds needs a visible, reachable way to pause, stop, or lower its volume.
Outcome
On a video-conferencing app's meeting controls, this barrier is gone for screen-reader users competing with page audio — they can finish what they came here to do.
Who is affected
Screen-reader users competing with page audio, and people with auditory sensitivity.
