I have also the same problem.
Did some of you have ever solved this issue?
Do we have to replace the amplifier IC TFA9896B (IC-Audio AMP - 1201-004228) ?

In a40 1st - it's a check buzzer pads
If any lost - check flatcable and system connector on mainboard

The ringer speaker stopped working after the phone got water damage.

The speaker is already replaced and did not help, the pads and main flatcable do make contact from speaker points all thru till the main hirose connector.

So I suspect that the SMA1301 amplifier chip that got damage.
