Earpiece not working after drop, any IC?

Hi,

I have big problems with a phone that have been dropped.

Screen and battery is replaced (was totaly damaged) and after this the earpiece is not working at all.

I have changed both the front flex several times and the earpiece without success. Done a visual inspection on the board without to find anything.

Is there any IC, resistor etc that handle only the earpiece?

All other sound works great, so nothing like the iphone 7 sound ic problem.

Thanks!

These are the lines that are responsible for the ear speaker. You’ll want to check the filters on these lines and the continuity between these lines and the connector.
