<video> or <audio> elements must not play automatically
What is the problem?
The "no-autoplay-audio" rule ensures that audio does not automatically play, instead a user should explicitly play the audio.
Impacted Groups
Why is this important?
Unexpected audio can be disruptive and frustrating for users, especially those in public settings or with auditory sensitivities. It can also interfere with other audio sources, such as notifications or spoken content from screen readers.
How to solve this issue
To fix this issue, avoid autoplaying audio for more than 3 seconds. If autoplay is necessary, provide a clear and easy-to-use control to pause or mute the audio. This gives users the choice to control the audio playback and prevents unexpected interruptions.
