Mac OS XGo 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 the digital mode.
3. Reset SMC.
Choose the method for “On Mac notebooks with non-removable battery”.

Try cleaning out the headphone jack and then insert a headphone several time. Sometimes the jack gets stuck.
Sound problems
In the Terminal, type that:
sudo killall coreaudiod
And in the sound preferences, make sure your internal speakers (and not HDMI or other device) is selected.
