HELP!!! After jail broke 4.3.1 (Redsn0w) and installed Cydia and among other apps. I used to have audio (keyboard,games,alert, etc). But something went wrong yesterday, after I installed a bunch of apps. When playing movies, I have audio and could control the volume up and down. HOWEVER, when playing games like Angry Birds, Ninja fruits and other games. The notification alert sound is now silence as well. I have no sound and can't control the up and down volume button. Could someone please explain what happened here?
