Iphone Sound

Hello Apple Support Community. I have a question. Hoping one or more of you might be abe to help.

When sliding off the 'silent' button the phone registers the fact that the headphones are now engaged.

They are not connected and I cannot get the speakers to work. When I plug in (apple) headphones I can

hear my music. When I disconnect them there is no music and then the screen registers that the headphones

are still connected?

Any Ideas?

Many thanks

Paul
