How do I simulate audio autoplay in IOS devices?

I have a problem with audio on the iPad/iPhone IOS. Using Edge Animate, My site works well on a desktop browser -- the goal is to have audio play when the site is viewable -- sort of an "autoplay." I don't want the user to have to press a button to start the audio. Knowing that autoplay is non-functional in IOS, I disabled it and place an ACTION on the timelime at 0.1 second to play the audio. It works fine on the desktop browsers.

BUT, this, too, does not work on IOS. I thought a PLAY action on the timeline would start the audio in IOS -- but, it doesn't. What am I doing wrong? Please.
