My sound doesn't work and all my output devices in sound settings are gone.

[Sean]

I was working on installing different themes for my desktop and after uninstalling one of them my sound stopped working. I check the sound settings and all my output devices disappeared. The icon disappeared unless i refreshed the toggle on the sound settings menu, but its just the speaker icon and there's no sound waves or x coming out of it, yet it says that it's muted.
