Audio codec ICs and amplifier chips that fix microphone, speaker and call audio faults.
Audio codec ICs and amplifier chips control the phone's microphones, earpiece and loudspeakers, and a faulty audio IC can cause no sound, no microphone, a greyed-out speaker button or failed voice recording. On some iPhone models, the audio IC is known to fail after drops due to board flex. Replacing an audio IC requires a microscope, hot air station, BGA stencils and solder paste. Match each chip to the exact phone model and IC part number before ordering.
