If the headphone jack is not working on your MacBook, you should check the headphones jack for detecting the issues. Sometimes, dust or fluff may block the port due to which your headphones do not function properly. You should remove the dust from your headphones before using them.

The easiest way around this is to remove your headphones, then either tone it down or muffle it while the sound is playing through internal speakers. OS X has separate volume settings for headphones and internal speakers, so when you muted internal speakers, the audio should not be playing if you have lost your headphone connection.
If no speakers appear on your Mac, connect a pair of headphones to the Mac, play a song or whatever sound you want, and then shut down your Mac. To correct this, you can leave a set of headphones connected, and then click on the “Output” tab to choose speakers. If the ports are blocked, that will prevent your Mac from playing audio via headphones. Sometimes, the MacBook Pros speakers will not work because something is blocking the headphone port.
