But why? To my understanding the reason is that Apple attaches the sound-on-or-off-state to the current output device. So switching off the sound while having plugged in the headphones makes the headphones be silent. Plug them off and you will hear the internal speakers. Plug them in again after a minute or after half a year and they still will be silent.
Its state depends on the selected output device. Most likely the audio is being directed to some other output device like Soundflower or Boom. Just make sure that Headphones is selected.

How to get a Mac laptop's headphone jack to work reliably | Macworld
My headphones will not work when I pug them in. The most common occurrence of this problem is on pre Macs that had a digital audio output support in the headphone jack. On those Macs, there was a sensor in the port that detected whether a headphone jack or a digital audio device was plugged in. The Mac would then change the output to headphones or digital output accordingly.
However, sometimes the sensor failed to recognise when a digital audio device had been unplugged and so the audio output remained locked on digital output, with no way to change it. With no digital audio output connected, there is no way to change the volume or hear sound. The solution in that case is to plug the cable back in to the socket and remove it again. Try blowing on it to remove any dust. Put the swab into the headphone jack and clean it, wiping away as much of the link as possible. Your Mac can play audio wirelessly via Bluetooth, so if you have Bluetooth speakers or headphones, you can use those to listen to music, or anything else on your Mac.
If you check the box labelled Show Bluetooth in menu bar in Bluetooth preferences, you can connect from the menu bar item. Once your headphones or speakers are connected, click on the volume control in the menu bar and choose them. To conclude, there are a number of reasons why the sound is not working on your Mac.
