If the built-in speaker is not producing any sound, verify that no external audio device is connected to the Mac through Bluetooth or the headphone jack. Likewise, make sure that the media file you are trying to play is not disabled by default. Try playing other songs or videos and check if there is sound production. If the audio output is still very low or no sound, continue with the solutions below.

1. Change sound preferences

4. Reset NVRAM / PRAM

Information about your Mac’s display resolution, speaker volume, and startup disk configuration is saved to non-volatile RAM (NVRAM) or Settings RAM (PRAM). Interestingly, there are many software and hardware issues that can be resolved by resetting your storage unit.

If you notice that your MacBook’s speaker volume is abnormally low or not as loud as before, follow the steps below to reset NVRAM or PRAM.

Note: Resetting NVRAM and PRAM on a MacBook follows the same steps (described below). Second, you may need to reconfigure some system preferences and settings after performing an NVRAM reset.

Your Mac’s speaker volume should now return to its default state. Try to play a song and check if the low volume issue has been resolved.

5. Check the application settings

Some apps have their dedicated playback volume control which is completely independent of your Mac’s volume control. Take for example the Apple Music app. In the upper left corner of the app is the volume slider. If the app volume is muted, there will be no audio output, even if your MacBook’s built-in speaker (or external audio device) is set to the maximum volume level.

Is the problem specific to a specific application? Or is it system-wide? For example, if your Mac’s speaker doesn’t work with Apple Music, try playing a YouTube video on a browser.

There are cases where a particular app will not stream audio to your Mac’s speaker while other apps are working fine. In this case, force quit the errant app and open it again. Open the application and use the keyboard shortcut ‘Option + Shift + Command + Esc’ to force quit the application. Otherwise, tap the Apple logo in the menu bar when the app window is active and select Force Quit from the menu.

Finally, make sure you’re running the latest macOS on your MacBook. Go to System Preferences> Software Update and click the Update Now button.
