The title says it all. In the game, I have no sound except for the in-game music, whether it's in a world, in the title screen, or in the options screen. Even with all sounds at max and the music set to 0, it doesn't work. If it helps I have a speaker and headphones, both have the same issue and F3+S doesn't fix it.
