If your MacBook speaker is not working, start by separating software issues from hardware faults.
Quick checks
- Verify output device and volume settings
- Test with headphones
- Restart and test in Safe Mode
Hardware causes
- Speaker damage (liquid, dust, impact)
- Flex cable / connector issues
- Audio circuitry issues on the logic board (less common, but possible)
If sound is distorted or missing after software checks, contact iQube Tech Care for diagnosis.
