Preparation guide

  1. Check the app’s own volume and mute controls. Try another known audio file to separate a silent file from an output problem.

  2. Disconnect headphones and external speakers. Check whether a connected display or Bluetooth device is receiving audio.

  3. Open System Settings (or System Preferences on older macOS) → Sound → Output. Select the MacBook Air speakers, raise volume carefully, and clear mute.

  4. Replay the same known file and compare the result. Keep whether the built-in speakers were selectable and whether another output worked.

Check the result

  • Save the selected output and volume finding. Recheck before reconnecting a dock or headset.
  • If the built-in output stays silent with known audio, contact Apple support. Do not infer the amplifier or speaker assembly from this alone.

Stop conditions

  • Stop using and charging a swollen or damaged battery. Do not open, compress, puncture, or attempt battery removal. Contact the manufacturer or a qualified service provider.
  • Disconnect a damaged accessory if it is safe to do so. Do not open a mains power adapter.
  • Save accessible data before restarting. Do not reset, erase, flash firmware, bypass a lock, or open the enclosure in this task.
