Go step by step and test.


 1. System Preference > Sound > Output > Internal Speakers

    Highlight  Internal Speakers.

    Make sure that Mute is not enabled.


 2. Plug in and  remove the headphone.

    If you see red light in the headphone port, plug the headphone

    in and out of the port 5 or 6 times to flip the microswitch inside.

    Sound output may be stuck in digital mode.


3. Reset PRAM.   http://support.apple.com/kb/PH18761
