speaker and audio is not emitting sound
I've been having this iPhone 4S for more than three years and just now my sound is keep on cutting off every time i try to make a call or use my headphones to listen to music. It is very irritating and i tried to reset all my settings and will not work. It only works when one of my notifications buzz and i can hear the sound but after all my notifications go crazy the sound is lost. I don't know what to do.
