Sound not working on Chromebook

[Stormy]

Hello! I'm quite new to Linux so I don't have much idea about this. Sound was working correctly on Chrome OS, but when I downloaded Linux Lite stopped working for no reason. I already tried changing the audio card on Alsa and I also made a speaker-test, and apparently everything was correct. I checked if everything was okay on Pavucontrol and still nothing found.

I'm so sorry if this is easy to fix but I literally have no idea.
