No Sound on MacBook. How to Fix It?

Apple equipment is reliable and easy to use, but these are not the only advantages of the MacBook. Many users praise the sound of the speakers on the Mac. Engineers from Cupertino pay a lot of attention to the sound system. In Apple computers, it is very complex. That’s why sometimes it malfunctions, causing sound not working on Mac. We have studied this topic. In this article, we will describe the reasons why sound not working on MacBook. You will also learn about the ways to solve this problem on your own.

Reason №1: Operating System Failure or Incorrect Sound Settings

MacOS is considered one of the most advanced operating systems in the world. But it can also have glitches that cause sound issues.

There are several reasons for audio loss due to the operating system or system settings failures:

  • Installation of third-party audio processing software (players, audio recording and editing software);
  • Faulty macOS or EFI firmware upgrades (bad Internet connection, sudden power outage);
  • Kernel errors in the system;
  • Incorrect setting of audio parameters.

In addition to issues with the operating system, the lack of sound in macOS can also be caused by incorrect settings. For example, the system may have selected external speakers that are not currently powered.

Sometimes the system redirects the sound to a wireless audio system (Bluetooth), where the volume is turned off. Of course, the situation is trivial, but our task is to completely exclude all the obvious causes.

If your MacBook has no sound, open System Preferences > Sound, or go directly to this item from the top panel of macOS. Check if the Output Device is set correctly in the Output tab.

To check, turn off your headphones, select the built-in speakers, set the volume to maximum, and try playing any system sound or an audio track in one of the standard formats (e.g. AAC, MP3). Files in unsupported default formats may not play correctly due to an outdated or corrupted driver version.

If that doesn’t help, try temporarily disabling all Bluetooth sync connections and deleting pairs. Clearing the NVRAM is done by a combination of keys Alt + Cmd + R + P when turning on the device (hold the keys from the moment the device is turned on until the greeting sounds again). Sometimes this removes all temporary system files and solves the problem.

If your MacBook has no sound after the above steps, you should look for a hardware malfunction.

Reason №2: Damaged Speaker

Often speakers do not work on MacBook Pro because they are broken. The speakers in all Apple devices not only have quality sound, but they also have a long lifespan. Nevertheless, the malfunction can still occur due to several reasons:

  • Continuous listening at maximum volume or with programmed amplification of certain frequencies (after several years of intensive use);
  • Mechanical damage;
  • Contact with liquid (individual components oxidize, speaker diaphragms lose their properties);
  • Voltage fluctuations (the electronics inside the speaker housing malfunction).

Note that the speakers are virtually unrepeatable if mechanically broken.

There are other reasons why the MacBook Pro has no sound. Sometimes moisture or foreign objects in the headphone jack (3.5 mm) cause a short circuit. Then, the system incorrectly detects connected external speakers or headphones, regardless of whether the device is plugged into the laptop’s jack. Cleaning the plug itself with a special cleaning agent or removing foreign particles from the plug can help in such a situation. If the problem persist after replacing the plug, then the motherboard and other components are the cause of the problem.

Resume

There are several reasons why there is no sound on Mac. Most often, the issue is in the sound settings or in the operating system failure. In 80% of cases, sound can be restored by rebooting or other manipulations described in this manual. But if none of these methods helped you, the issue can be due to hardware. In this case, you will need to replace the speakers or another element of the audio system.
