I'm trying to autoplay an audio file within a survey utilizing web app. I can't find any example of this online. I'm sure the functionality is there, but I don't know how to get it to work. Any help would be greatly appreciated.
I wouldn't expect this to be readily possible as most modern browsers have restricted the auto-play of audio and video on websites. I remember this coming up with Story Map Cascade and videos, when the browsers cracked down.
I would recommend making the audio button clearer / encouraging the users to press the audio button.
I also wouldn't recommend autoplaying audio or video, even if it were possible. It's generally not an enjoyable user experience.
