Audio IC / No Sound Repair
Voice memos not recording, callers not hearing you, or greyed-out speaker button are classic signs of an audio IC problem. We repair the logic-board audio circuit to bring back microphone and speaker functions.
Symptoms of Audio IC Failure
Typical Issues
- Speaker button is greyed out during calls.
- Voice memos cannot start recording.
- People cannot hear you, or you cannot hear them.
- Random reboots when using camera or audio apps.
- Started after drop, bend, or long-term heavy use.
Our Repair Process
- Confirm audio IC-related faults with testing and logs.
- Lift and reball / replace the audio IC using hot air station.
- Rebuild cracked pads and under-IC jumpers if needed.
- Test all microphones, speakers and sensors before re-assembly.
- Final call test, voice memo and video recording test with customer.
Using the phone with a failing audio IC can make the damage worse over time. Early repair gives a higher chance of a clean fix without needing a replacement board.
