Out of nowhere, sound stopped working for me. My most current save is at the boos fight in chapter 3. It used to work just fine, and when I started it up today, the not-game is completely silent. No narrator on the title screen, nothing. It's just this game, though, and sound is working just fine in all other programs.

Any ideas?

Okay, now I feel stupid. I have no idea how this happened, but somehow the Ting process (the game window) had become muted in the Windows sound mixer. That revelation came upon me right after posting that last post, so I guess posting still kind of helped me find the solution. In a very circumvent, adventure game kinda way.
