Sound stopped working

on my pi 400, the audio randomly shut off, and in the settings it said everything was working normally. I used another device on my TV and it worked, so it wasn't my TV, I shut down and switched to the pi OS and it worked too, meaning it has something to do with the OS. btw im on 21.10
