Some experiences depend on timely or ambient media
Muted previews, live broadcasts, games, exhibits and dedicated media services can use motion to explain context or meet a visitor’s reasonable expectation without surprise sound.

COUNSEL FOR
Playback should begin with the visitor
W3C accessibility guidance warns that automatic audio can interfere with screen-reader output and requires controls when it continues beyond a short period.
Unexpected media consumes attention and potentially metered data before a visitor has chosen it, while a labelled play control preserves access to the same content.
Chrome’s autoplay policy already blocks many unmuted starts unless there is prior interaction or an established media expectation, reflecting a broader preference for user control.
COUNSEL AGAINST
Some experiences depend on timely or ambient media
Muted previews, live broadcasts, games, exhibits and dedicated media services can use motion to explain context or meet a visitor’s reasonable expectation without surprise sound.
An additional click can be a barrier for hands-free displays, kiosks or people using some access setups; browser and device preferences may handle the choice more consistently.
A blanket ban can punish legitimate formats while intrusive publishers find other ways to demand attention. The distinction between sound, motion and user intent matters.
The judge’s direction
What the evidence can — and cannot — settle
Unexpected sound should be off until the visitor acts, and non-essential moving media should offer an obvious pause. Muted previews may be reasonable where motion is expected and accessible, but every site should work when autoplay is blocked.
