If the problem is related to headphones (the phone says on volume control headphones)just clean the head phone jack

If the problem is about the disappearance of the volume bar... Clean the dock well without destroying it using needle/toothbrush and sometimes alcohol to dissolve the dirt... I had both problems on different occasions and I solved both problems in that way !!
