Make sure the sound isn't muted. Press the volume adjustment buttons on your keyboard, including Mute, or check the volume slider at the top of the screen.

Unplug any peripherals. Headphones, speakers, and other devices can stop audio from coming out of your MacBook's speakers. Disconnect them to see if the sound comes back.

Check the sound preferences. Audio might not work if the sound output is configured incorrectly. Open System Settings, and then go to Sound > Output. Choose MacBook Speakers, MacBook Air Speakers, or MacBook Pro Speakers, depending on what kind of laptop you own.

At the bottom of this window, make sure the Mute checkbox is not checked. Restart your MacBook. The problem may be that your MacBook didn't initialize the sound drivers correctly when it booted up. A restart can give it another chance to start everything properly.

See if macOS needs an update. The sound not working on your MacBook may be a bug in the current version of macOS. Reset the NVRAM. Depending on what kind of MacBook you have, it may use non-volatile RAM (NVRAM) to store specific settings. Like any other memory, it benefits from an occasional reset.

What you'll reset depends on your processor: If you have an Intel Mac, reset the NVRAM by shutting down the computer and restarting it while holding Command + Option + P + R.

If you have a MacBook with an M1 chip or later, it still uses NVRAM, but you can't reset it using this method. A normal restart should take care of it automatically. Contact Apple. If your MacBook's sound still isn't working, it may need servicing. You can take it to an Apple Store or an authorized repair place, either of which should be able to diagnose and fix the problem.
