Auto-playing Audio
Audio, such as background music, that automatically plays when a user comes to a web page can be very distracting and will interfere with screen reader audio. WCAG 2.0 Level A requires that “a mechanism is provided to stop, pause, mute, or adjust volume for audio that automatically plays on a page for more than 3 seconds.” It is usually better to not automatically play audio, but allow the user to manually play the audio if they choose.
