Audio is gone...

Hello!

One of our apps (the music box) people sometimes complain that the audio never shows up (ie: the person install, and no audio sounds, ever).

It only happen on iPads it seems (both 2 and 3 I am sure… 1 I am not sure yet).

Some users we even made them test other apps (including other Corona apps), and they said they were fine.

Any clue on where I should be looking?
