Good day,
My app is a music playing app. I control the <audio>-Tag with Javascript. So far no problems, play, pause, next and previous buttons are working. When I stand-by the device in iOS 5, the music keeps playing, but the automatic next song doesn't work. When it isn't in stand-by, it works. And in iOS 6, just after pressing the button, the music fades out.
The Play/Pause button on the lockscreen works in iOS 5, but not in iOS 6.
