I have a rather odd problem cropping up in a couple of the games that I play. AI Factory Limited's Backgammon (the purchased one), Jigsaw Puzzles by Titan Inc (again purchased version), and Sudoku by Jason Linhart. Only some of the sounds play. It is very annoying. If I reboot the tablet they will all play again. I would say that about half sounds play and the other half do not. I do not have problems with playing music, audio books, or movies. I also have not noticed it with any other App that happens to have sounds. Does anyone have any ideas? Oh, this is on a Samsung Galaxy Note 10.1 running stock OS.
