and Im still stuck. Im building a streaming-video app to be used on an internal network over Wi-Fi - absolutely choked by this limitation.
Gonna send a bug report.

I agree... the result of this lock down is inconvenience... theyre just making it harder to step away from Flash... irritating

Apple is playing games here. There have been work-arounds for the autoplay issue that worked with earlier versions of iOS and have since been cleaned up by Apple. This shows that having this feature available threatens some position of theirs, in the grand scheme of things. It takes effort to write-out as it does to write-in.
So why not have a opt-in system for video auto play. Similar, in operation and location within the settings interface of iOS, to the Fetch new Data dialogue. This would take care of the posited argument of mobile users being hit by unwarranted band-with charges due to video autoplay. This is exactly what is being addressed by Fetch new Data settings.
The only reason I can logically think of here with all of the info Ive been able to glean on the subject is that video autoplay is the only arguable point within the whole HTML5-CSS-JS framework that can keep the iOS App at any form of advantage, by Apple excluding its functionality in mobile Safari.

But in my case, I dont even want to download any file. I just need to be able to PLAY a SYSTEM BEEP / Sound automatically from a Web Page via Javascript or any other means.
Please help !!
I am still NOT able to Autoplay an audio file with all the suggestions on the Web.
All I want to do is Play a Sound (mp3 or System beep, anything) Automatically when a page is loaded. I understand that autoplay was disabled for some ATT and Charges related reasons. But playing system sounds has no charge / download. Why cant I do this ???
