My daughters iphone 4 speaker was a little distorted but worked so i decided i would order a replacement*

I then installed the new speaker (speaker only i had to reattach signal antenna)But i get no sound from phone at all*

So i figured possibly a defective part so i re-installed the old speaker which then presented me with he same problem no sound at all*

Every other function works it plays music on dock charges earpiece works mic works everything except loudspeaker*

Anyone have any idea what this could be
