Using mint and SOMEHOW speaker audio works

Basically, an hour ago it was about to rain and I found some earphones on the ground and decided to stea- I mean take it home, and then after cleaning it I placed the jack into my Chromebook and messed around in helvum trying to get the microphone to work in a game, and lo and behold, MY SPEAKERS RANDOMLY WORKED

I am using a c733 Bobba Acer Chromebook with mint(which is unsupported)

(Also if I take out the earphones it stops working)
