This works fine for me on a 7/1/2013 Partner Build. I am noticing that after returning back to the game after going to the lockscreen, the game sound won't resume until a new page is gone to.

What build are you running?

Expected behavior from bug 828283.
Any app should stop audio if they want -- by using visibilitychange event.

Jason, the issue is when you lock the phone when playing games with music, the music of the game continue playing even in phone locked state.

I believe games in phone locked state should not play any music. It causes a drain in battery.

Please let know if a separate bug should be raised w.r.t "Cut the Ropes" application to fix this behavior.

Fix this by "disallow all audio playing" when device locked would be a bad fix because there's no way to un-mute it since we mute all. Allow every audio in focus could be played and let the apps turn off sound by themselves is not a perfect way but better to go.

I don't think there's a general fix here unless we want to back-out bug 828283.
We don't know who is playing game sound and who is playing music sound if they are all using normal audio channel, from system. And I don't think we should invent a new channel for this case.

Sounds like the conclusion we've reached in this bug is that this is a TE bug on Cut the Rope.

As you said in comment 2 jason, this issue cannot be reproduced on the latest build. There was some problem with receiving visibility change events for external-apps. Now it seems to work.

Thanks for your efforts. Marking this issue as invalid.
