My Internal Speakers Are Broken On MacBook Pro

Is there a red LED glowing in your headphone jack? On the left side of your computer.

Try a PRAM reset.

Flow these troubleshooting tasks and let me know how it goes:

Check your Sound System Preferences pane

If you are still having issues after you have confirmed the proper version of Mac OS X is installed, make sure the computer is set to play sound from the right source.

1. Remove any external audio devices and cables from the USB, FireWire, or 3.5 mm audio ports.
2. Open System Preferences from the Apple () menu, the Dock, or from the Applications folder on your hard drive.
3. Open the Sound pane and the Output tab, then select Internal Speakers as in this image:
   
   1. If Internal Speakers is not an option proceed to step 4. For Mac Pro computers, proceed to step 5.
   2. If Internal Speakers is present but not selected, select it and test again.
   3. If the Output volume slider is low or the Mute box is selected, raise the volume slider or deselect the Mute box and test again.
   4. If the issue continues through these steps and Internal Speakers remains the selected option proceed to step 5.
4. If the Internal Speakers option does not appear in the Output tab and your computer is not a Mac Pro, check that Digital Out is present as in the image below:
   
   1. Confirm again that all external audio devices and cables have been removed.
   2. Check to see if a red light is lit in the line-out port. If so, your Apple computer may need service.
   3. If you do not see a red light, proceed to step 5.
5. If the issues persist, contact Apple support for further troubleshooting assistance.

Thank you, is your problem resolved?

what is the red led from the headphone jack from, i have that and my speakers do not work please help

The red light indicates that the audio output switch is set for the audio output port and the internal speakers are turned off. It can be tripped sometimes by several insertions/removals of the earphone jack. If that fails, use a thin object such as a toothpick, cocktail stirrer and the like and juggle it inside the port. If still no success, take it to the Apple store.

This solved my problem! Thank you so much! I was starting to get frustrated with this. . .

Hello,

I am having the same issue...internal speakers are not working on my MacBook Pro (purchased Aug 09). I tried a PRAM restart and I've tried putting the headphone jack in and out several times, as well as wiggling around a toothpick in the port. None of that seems to have worked. There was a red light emitted from the port a little while ago but now it's gone.

Any ideas?

Thank you!

Same problem for me. Toothpick did the trick. Thank you for the help.
