How to fix Mac speakers problems

Here’s what to do if your Mac speakers stop working:

1. Play something: To begin, make sure there is no sound coming from your Mac by playing something in Music (Music replaced iTunes in macOS Catalina, so if you’re using an older macOS, you’ll want iTunes). Play Music Select any track from your music collection by clicking on Songs. Even if you can’t hear the music after pressing Play, you should see the bar progress.
2. Make sure you didn’t turn the volume down by pressing the Volume Up button, which is usually located on the F12 key in the top-right corner of your keyboard. When you tap this, an overlay should appear on your screen, indicating that the volume is increasing.
3. If you’re in the Music app and notice that the volume slider is far to the left, drag it to the right.
4. If that doesn’t work, try clicking on the Volume option in the top-right Menu bar. This will be in the Control Panel section of the menu bar if you are using Big Sur or Monterey. Slide the sound slider to the right.
5. Examine a different app: It is possible that sound is playing in iTunes or Music but not in Safari; this could be due to Safari’s sound being turned off. If you’re watching a video in Safari and there’s no sound, you should be able to adjust it from the video window’s sound controls. The video may be muted by default, forcing you to select whether to hear the sound.
6. Turn off and on your Mac: Sometimes restarting your Mac will solve a problem like this.
7. Examine your headphone socket for earphones: Make sure there are no earphones connected to the Mac. Remove them, and you should hear sound coming from Mac’s internal speakers.
8. Examine your ports: Disconnect everything plugged into your Mac, not just the audio port, because Thunderbolt, HDMI, and USB devices may be channelling audio. Remove any cables that are plugged into those ports as well.
9. Examine the headphone jack for debris (a red light may appear in some models): Something like fluff or dust could be clogging the port. If the port is blocked, the Mac may act as if headphones are connected. Try blowing into the port to see if you can get whatever it is to move. Then, while pressing and holding one of the volume buttons, plug in some headphones to see if that solves the problem.
10. Software updates: Check that your Mac is running the most recent version of macOS.
11. Restart the sound controller as follows: Open Activity Monitor, find ‘CoreAudio’ in the list of processes, select it, and click the X to terminate it. The process will restart immediately, which may resolve your issue.
12. Examine the System Preferences: Click Sound in System Preferences. Select Internal Speakers from the Output tab. Make sure the Mute button next to Output Volume is not muted (there should be no tick in the checkbox). Make sure the Output Volume slider is all the way to the right.
13. No internal speakers? If you see Digital Out Instead of Internal Speakers in the window, unplug everything from your Mac (as above). If Internal Speakers is still not listed as an option in the Output window, you should contact Apple Support.
14. Resetting the PRAM: This procedure can resolve some sound-related issues. Hold down Command, Option (or Alt), P, and R while restarting the Mac. Hold them down until the computer boots up and chimes. Hold them down until it chimes again, then release the keys.
15. Reset the System Management Controller (SMC), as described here.
16. If this does not resolve the issue, you should have your Mac serviced because it could be a sign of failing hardware.
17. If none of this work, consider returning the Mac to the Apple Store and having the hardware checked out. Here’s how to schedule a visit to an Apple Store.
