Keep the volume low. Keep your work.
Save open documents and pause calls or recordings. Note whether the sound stopped after connecting a display, using a headset, installing audio software, or a drop. Use familiar speech or music at a modest level; repeated full-volume tones are unnecessary.
If the MacBook is wet, unusually hot, smells burnt, or has a bulging case, stop audio testing. Disconnect power if safe and seek assessment. Follow the laptop spill guide for liquid exposure. Do not keep restarting it to see whether sound returns.
Check the player before the speaker
Start playback deliberately. Check the volume and mute control inside the app or webpage as well as the Mac’s volume. In Music, use the slider at the top. In Safari, a muted page can be unmuted using the Audio button in the search field. A video player may also have its own separate mute button.
Try another familiar clip or song in a second app. If possible, use an already downloaded file so a stalled stream does not confuse the test. If just one file fails, try that file on another device. Apple recommends comparing media as well as checking app volume.
- One app plays clearly through the MacBook
- The built-in audio path works for that playback. Return to the silent app’s player and output controls. Do not order speakers based on that one app.
- The same file is silent elsewhere
- The file or its audio track deserves attention. This result does not establish a MacBook fault.
- Both apps remain silent
- Check the selected output next. A moving playback timer alone does not prove the Mac is sending audio to its internal speakers.
Only a meeting or call app is silent?
If ordinary media works, inspect the call app’s speaker/output selection and use its speaker test, if offered. Select the MacBook’s speakers explicitly for this comparison. The microphone/input choice controls what others hear, not what you hear. Do not change microphone permissions to fix silent playback. Follow that app’s official help if its test still fails.
Choose built-in speakers explicitly
Pause playback. Unplug wired headphones, USB audio interfaces, and external speakers. Disconnect an HDMI/USB-C display or audio dock for this test if practical. If the dock also holds a drive, save files and eject that drive in Finder before unplugging it. Keep the laptop open so you can use its own screen.
Use the menu for your macOS version
- macOS Ventura 13 and later: Apple menu → System Settings → Sound → Output.
- macOS Monterey 12 and earlier: Apple menu → System Preferences → Sound → Output. Apple’s Monterey instructions call the device “Internal Speakers.”
- Choose the MacBook’s speakers. The name can include the model, such as “MacBook Air Speakers”; look for the built-in speaker device rather than a display, AirPlay receiver, or headset. Raise Output volume moderately and clear Mute if selected.
Wireless outputs can remain available after cables are removed. Select the built-in device even if AirPods or an AirPlay destination appears in the list; there is no need to forget paired devices or turn off all wireless connections. Apple’s internal-speaker checklist covers external connections, Output, volume, and Mute.
The volume control is unavailable, or sound goes to the display.
Read the selected output’s name first. Some digital outputs use the receiving device’s own volume controls. That is different from a failed MacBook volume key. To test the laptop, select its built-in speakers and replay the same clip. If you actually want display or external-speaker audio, use that device’s power, volume, and model instructions instead. See Apple’s output settings guide.
Let the result narrow the next step
With built-in speakers selected, replay the two-app comparison. Listen briefly at a comfortable level and record the result before changing anything else.
- Sound returns after selecting built-in output
- Routing explains this test. Reconnect accessories one at a time, checking Output and replaying the clip after each. This can identify which connection changes the destination without blaming the dock or speakers prematurely.
- Headphones work; built-in speakers do not
- Audio works through a different path. Recheck the built-in selection after removing headphones, then try the normal restart below. This comparison cannot distinguish speaker, connector, or software faults by itself.
- Built-in output is missing, or both apps are still silent
- Record what Output lists. Restart once if the Mac is otherwise safe. A missing entry is a useful observation, not proof that a particular part needs replacement.
- One side is quiet, or speech crackles in both apps
- Check the output’s Balance control is centered if shown. Stop loud testing if distortion persists. A working headphone test does not rule out a problem in the built-in speaker path.
Save, restart, and repeat the comparison
Save work, finish transfers, and choose Apple menu → Restart. Follow any save prompts. After signing back in, check Sound → Output again and replay the same clips before reconnecting audio accessories. Apple documents this normal restart.
A restart is not an erase or reinstall. Holding the power button to force a shutdown can lose unsaved changes; it is unnecessary for a responsive Mac. These app and output checks are the same on Intel and Apple silicon MacBooks. Do not apply an unrelated model’s SMC or startup-key reset sequence.
Bring observations, not a guessed part
If built-in sound remains missing, silent, or distorted after the comparisons and one restart, arrange assessment with Apple or Hailey Device Repair. Stop sooner after physical or liquid damage. On a work or school Mac, involve the administrator before removing audio software or changing a managed setup.
Share the model and macOS version from Apple menu → About This Mac, when the problem began, selected output, two apps tested, and whether headphones worked. Crop personal information from screenshots; there is no need to publish a serial number.
Back up important files before service. Do not erase the Mac, reinstall macOS, delete audio preference files, or install a “driver fixer” as a prerequisite for these checks. If a later repair plan involves data loss, confirm the backup and understand that plan before proceeding.
Sources & scope
Official Apple guidance checked October 15, 2026. This is a source-based owner checklist, not a hands-on diagnosis. Labels vary with macOS and the connected hardware; the comparisons above are clues, not a component test.
- Apple: Internal Mac speakers not working — app controls, connections, and built-in output; updated March 30, 2026.
- Apple: Cannot hear sound from Mac speakers — compare media and output types; Monterey version for older menus.
- Apple: Sound output settings — available destinations, volume, and balance.
- Apple: Shut down or restart — normal restart and forced-shutdown data risk.
