--- Comment #2 from Ashley Gullen <ashley at scirra.com> ---
This affects a huge amount of existing web content. All Construct 2 content, and as far as I can tell all Phaser, soundjs and howler.js content is affected, because all these frameworks rely on touchstart to unblock the Web Audio API.

I have made two test cases:
https://www.scirra.com/labs/bugs/iosaudio/touchstart.html - unblocks in touchstart event, only plays audio in iOS 8 and older

https://www.scirra.com/labs/bugs/iosaudio/touchend.html - unblocks in touchend event, works in iOS 9 as well

More discussion here: http://www.html5gamedevs.com/topic/17326-ios-9-webaudio-issues/

I'd estimate most web content in the wild using the Web Audio API now remains silent on iOS 9, basically making it useless. This is a severe regression from iOS 8; us framework developers can distribute workarounds, but we cannot update all the existing broken content out there, Safari needs to be fixed as well.
