Hey, I recently reinstalled the game, and chose to disable the sound at the start. I'd like to re-enable it, but I can't figure out where to go.

I figured it out, for some reason I had to uninstall and reinstall it as an administrator to get it to work.

For anyone wondering how to solve this problem while using GOG Galaxy, I think I figured it out:

Go to More -> Settings and disable Cloud saves. Then uninstall the game, make sure that the folder is completely gone. Now reinstall the game and it should ask you again what language you want to have and whether you want sound enabled or not. If this is the case, you can re-enable cloud saves again and upload you current game saves.
