Music and audio that plays as the site loads presents a serious challenge to screen reader users. The audio from a movie created with Adobe Animate CC software can interfere with the end user's ability to hear the contents of a movie using a screen reader. As a result, it is important to make sure that the user has control over when music is played.
The simplest strategy for handling audio playback is simply to allow the end user to control audio with a play and pause button. Allowing the end user to initiate audio provides the experience of the audio without creating an additional hurdle.
