Internal speakers on your Mac don't make sound
Possible Symptoms
- If you don't hear sound from the built-in speakers on your Mac
- Sound is cutting out or intermittently working
Possible Solutions
Make sure macOS is up to date and check your settings.
Use the latest version of macOS
The
first step is to make sure that you're using the latest version of
macOS. Back up your important information and then update the software on your Mac.
Check your sound settings
If you still can't hear sound from the internal speakers after updating your computer's software, check your sound settings.
First,
disconnect any external audio devices from your computer. Also
disconnect any cables from the USB, FireWire, or 3.5mm audio ports.
From the Apple () menu, choose System Preferences.
Select Sound.
Click the Output tab, then select Internal Speakers. If you don’t see Internal Speakers as an option in the Output window, this could be a hardware issue. Contact support to troubleshoot.
If the volume slider is set low, move the slider to the right and test again.
If the Mute checkbox is selected, deselect it and test again.
If you still don’t hear any sound, contact Apple Support.
Check the line-out port on your Mac
If the Output pane lists Digital Out instead of Internal Speakers, check the line-out port on your Mac.
