I'm having the same issue with my iPad 2. Sound with videos and such, but no sound in games.
Have you checked that notification mute isn't on (it doesn't affect iPod or Videos apps, but will affect most games and other apps) : depending on what you've got Settings > General > Use Side Switch To it's either set by the switch on the right hand side or via the taskbar - more info here http://support.apple.com/kb/HT4085
