O som não funciona - mint 19

Question

Alguns dias atrás, eu instalei o linux mint 19 ao lado do windows 10, tudo funcionou perfeitamente, até que eu liguei os fones de ouvido (enquanto eu estava usando o win10). Quando reiniciei o notebook, não consegui ouvir nenhum som.

Atualmente estou usando o kernel 4.15.0-33 - Eu tenho visto alguns problemas com diferentes, mas este deve estar bem ...
