Hi guys, I had my game exported to Xcode and build to my iphone, when I am playing the game and I receive a phone call, then when I go to back to the game, the game has no sound at all, or if I close my game for around few seconds then go back to the game, game has no sound too, so every time the game got suspended or interrupted, the game will have no sound. and here is the error message from Xcode. and also, I have 16 yellow warning messages too, Thanks very much for helping guys.
