Why can I hear only loudspeaker?

[iMore Question]

Why can I hear only loudspeaker on my IPHONE 5 ?

I am able to hear sounds only from my loudspeaker.

Earpiece speaker is silent.

Also headphones are silent when you connect them to the jack connector.

The jack connector seems to be without any response actually.

.........

I tried to this time:

Facory settings.(of course did not help)

........

Changed: the Front Camera and Sensor Cable

Changed: The Earpiece Speaker

Changed: the Dock Connector and Headphone Jack

Nothing helps .

.........

Seems like on the motherboar is something wrong.

Maybe any chip.

Any ideas ?

Can you tell me which chip is responsible for sounds and how them check or change ?

It's best to check the website of ifixit regarding this issue. I'm not familiar with the internal working of the hardware.

I hope somebody will come along with a better answer.

Good luck.

Ps: it's always best to have your phone fixed by a certified Apple Repair Service. It costs a little more but you will have a working device for certain.
