Ah! A [https://i.dlpng.com/static/png/6649599_preview.png|Where’s Waldo] problem!
First do you hear the Bong startup sound? If you do that tells us the logic board DAC is working
Second look at your System Preferences > Sound do you see in the ***''Output''*** section the two listed outputs: Analog and Digital Out? If you only see Digital then that’s telling us the headphone jack has a problem. Try plugging in a headphone do you hear your music or other audio? Putting it in and out may fix things. Sometimes the little blade switched inside get messed up and need a little work to fix either because they shifted or they are dirty

Sadly you can’t replace it as its mounted directly on the logic board. You may just need to use a set of speakers.
