Many apps on my iPad have no sound.
After ios5.1.1 update all of my downloaded apps did not run
After reset and reboot the iPad, they run fine with no sound
Is there way I can fix this problem
E.g., angry bird, temple run, cartoon network, ninja go, friut ninja hd, etc. ( no sound )
YouTube, talking Gina ( sound o.k. )
iPad 2 Wi-Fi, iOS 5.1.1, No sound on some app
