Ipad 2 5.1.1. Jailbroken


Hi all,
Probably been asked before but I have no sound from recorded video or FaceTime.
I can hear them but they can't hear me on FaceTime. Movies and music the sound is fine.
While recording, if I get close to the mic and talk loudly, play back recording I can just hear it.
Some suggestions are to do a factory reset, but I'm not wanting to do that in the event of losing me
Jailbreak and being updated to latest software: iOS 6.0.1.
Just wondering what or if any settings could of been altered by mistake that could be the issue:
Is there a thread already on here that could help me out with settings and stuff.

Any help or links to other threads much appreciated.
