Mac Sound Output Not Working: Troubleshooting

Identify the symptom and environment

Start by recording exactly what happens. Note whether the Mac is fully silent, whether sound works in some apps but not others, or whether audio plays through the wrong output device. Check the operating system version because menu labels and settings can vary between macOS releases.

Write down when the issue began and what changed around that time. For example, note if headphones were connected, a Bluetooth speaker was paired, an external display or USB audio device was attached, or a system update was installed. This helps separate a temporary routing problem from a settings issue.

Isolate where the fault occurs

First check whether the Mac believes an input device or output device is selected. Open Sound settings, select Output, and look at the list of available devices. If the intended speakers or headphones are not shown, the connection or device recognition is the likely problem.

Play audio in a second app. If sound works in one app but not another, the issue is probably the app's sound selection or volume setting rather than the whole system. If no app produces sound, the problem is more likely at the system level, connection level, or hardware level.

Try another output if one is available. For example, switch from built-in speakers to wired headphones or vice versa. This can show whether the fault follows one device or affects all audio output.

Try reversible fixes in order

Check the simplest controls first. Raise the system volume and confirm that the Mac is not muted. Look for a volume slider near the top right of the screen or use Sound settings. If the selected output is not the device you expect, choose the correct option and test again.

For wired headphones or external speakers, disconnect and reconnect the cable. Remove debris or damage from the connector as a possible cause, but do not force anything into the port. If the device uses its own volume control or power switch, confirm that it is turned on and not muted.

For Bluetooth audio, open Bluetooth settings and confirm the device is connected. If it is connected but silent, disconnect and reconnect it. If it does not appear, make the device discoverable and pair it again using the manufacturer's instructions.

Check the selected output in the app where sound is missing. Video call and recording apps often have their own speaker, microphone, and output device menus. Change the app setting from a default or automatic option to the specific device you want to use, then test the sound.

Try a different audio content source, such as a saved audio file or a different website. This helps rule out a silent stream, paused playback, or tab-level mute.

Restart the Mac. This can clear temporary audio routing or driver problems without changing your files or settings.

Confirm the result

After each change, play the same sound that originally failed and listen through the intended output device. Repeat the test with a second app to confirm that the fix works beyond one program.

Check that playback does not create unexpected background noise or distorted sound. Return to the original speaker, headphone, volume, and app combinations you used when the problem started. If the symptom is gone in those conditions, the fix can be considered confirmed.

If the problem remains

Keep notes about what you tested and what changed. Record which devices appear in Sound settings, which apps remain silent, and any error messages. This information helps support staff avoid repeating basic checks.

A persistent problem does not automatically mean the hardware has failed. It may still be caused by a system setting, app conflict, damaged cable, or device firmware issue. Contact Apple support or an authorized service provider when the Mac produces no sound on multiple outputs after the above checks, or when physical damage is visible.
