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

    Sound output may be stuck in the digital mode.

    If you have apple tv, it sometimes does not reconnect with the sound on your computer.

     

    Go into iTunes and at the top left hand corner, there is a button with a down arrow.  If you click on it, it will show 2 options - apple tv or computer.

     

    Click on computer and it should rectify the problem.
