Okay so this have been going on for a few weeks I use my headphones a lot and sometimes when I take them out there is no sound at all and the only thing I can do to get the sound back is if I restart the computer..

 

What can I do?

    in settings, go into sound, then go to the output tab.  Check to make sure the internal speakers are selected for output and if the mute box is checked.

    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.
