Tested on an iPad Air 2 running iOS 9.1. Press "Play music" then when you can hear the music, press either of the "set volume" buttons. Neither of them change the volume. The demo creates a new Audio() and connects it to a Web Audio context via createMediaElementSource() which is itself connected to a gain node. The buttons change the gain node volume and the Audio object's volume. Neither have any effect on the playback volume. Both options work in Chrome, Firefox and Edge on Windows 10.
This prevents Construct 2 content being able to change the volume of music in iOS.
