Autoplaying audio drowns out screen reader speech, startles users, and wastes bandwidth—providing user control is essential for accessibility and good UX.
Verify no audio or video autoplays on page load. If autoplay is essential, confirm media is muted by default and pause controls are immediately accessible via keyboard within the first few tab stops.
Remove autoplay attributes from media elements. If autoplay is required, add muted attribute and provide prominent, keyboard-accessible pause controls. Consider adding a global pause button for pages with multiple media elements.
Explain how autoplaying media interferes with screen readers, startles users with cognitive disabilities, and creates barriers for users in quiet environments or with limited bandwidth.
Review the rendered markup and interactive states that affect Avoid autoplaying media. Flag exact elements, roles, labels, focus behavior, or keyboard interactions that violate the rule, and note how to verify the fix with browser accessibility tooling or assistive tech.
