Project with timeline audio. Works fine on all desktop browsers, works fine on Android Chrome, but on iOS... silence. I know that apparently you can "wake up" iOS audio by playing a sound in a click event handler, and I've tried that. The event sound plays, but the timeline audio is still muted. I wonder if it's because the Flash HTML page is contained in an iframe?
This is for a distance learning project, so there will be dozens of individual pages. If the user really has to do a busywork touch interaction to enable audio on every. single. page... well, that's an insanely awful state of affairs.
why don't you test by opening (in ios) the html file published by flash .
