The sound no longer works on my computer, however when I check in system preferences it says everthing is fime, also the microphone still works. All I did was un plug my headphones from the computer. I did go to system preferences and changed it back to internal speakers, but that did nothing. Does anyone know what is wrong with the sound?
1 System Preference > Sound > Output > Output Volume
Make sure that the box Mute is not checked.
2. If red light is visible in the headphone port, plug the headphone into and out of the port
to flip the microswitch inside the port. Sound may be stuck in the digital mode.
3. Reset PRAM. http://support.apple.com/kb/PH4405
4. Reset SMC. http://support.apple.com/kb/HT3964
Choose the method for:
"Resetting SMC on portables with a battery you should not remove on your own".
5. If these steps do not work, plug in the headphone in and reset SMC.
6. Apple store.
Best.
