    Hopefully one of these steps should solve the problem.

    1. System Preference > Sound > Output > Internal Speakers

        Make sure Mute is not enabled.

     

    2. 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 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. Applications > Utilities > Audio MIDI Setup

     

        Audio Devices window

        Side Bar

        Click the Built-in Output.

     

        Under Mute any of the boxes checked? If so uncheck it.

     

        Option click the speaker icon, if present and select Internal Speakers.

    Best.
