My iPad 2 audio only works with headphones and orientation does not work at all

My iPad 2 volume button does not work with the integrated speakers of my iPad, once a headphone is connected to the jack output of my iPad the OSD volume displays fine and works to the external headphone but once the headphone jack is removed, there is no more a volume bar and the side volume buttons don't work at all, this has affected the screen orientation as well, screen does not orientate as well,

Please help
