I'm not sure about how you call a microphone. Do you mean speakers or earphones?

have you any sound from the phone at all? either on loudspeaker or earpiece during calls?

have you tried opening voice memo app and recording your voice then try play back?

I would've suggested returning phone to shop as may be under warranty.Otherwise I'd try replacing dock assembly or checking connector 4 pins. I think James bond also had this problem and it was 2 small (tiny) ?capacitors beside dock connector on motherboard. Have a look in that area. Search James bond at top to find his solution.

This is link to photo of part for noise reduction ( beside dock connector) I haven't had time to go through all his answers but James bond says somewhere it can be fixed with just fine wire and solder.... Take a look at his answers and vote his answer up if it helps!!
