iPhone 7 no sound on earpiece only during a call
Hi to all, first time stuck and out of ideas so here is my fist question.
Iphone 7 with classic audio ic problem, no audio device on recorder, long boot time.
Made the c12 jumper(this is maybe the 20th device I repair with this issue), I put back the ic, test quickly the recorder, it works, put back the phone, test a phone call, surprise, no audio from earpiece, if I put it on speaker there is sound, in headphones too. The earpiece works withe every other sound source like youtube, recorder, only on a call it is complete silence.
What I tried:
Changed the audio IC with another one, same thing.
Restore with itunes, nothing.
Changed the earpiece (I tried with another complete assembly screen), same thing.
Made diode readings from under the audio IC, it looks all good.
Now I don’t know what to check, it is an Intel baseband iphone 7.
Any ideas?
Thanks, Cristian from Romania.
