Penumbra: Overture, forever looping danger music

[Gamable]

Whenever I get to the part of the game were you have to turn on the generator, I go to the fence, and the dog appears and the danger music starts playing, but even when I go far away from the dog and even into other loading rooms(like the generator room), the music is still playing, even though no dog is present in the room. I have restarted the game, restarted Steam, restarted my computer, uninstalled and reinstalled the game, and even started the game from the beginning, but yet again, when I get to the generator part in the game, and I go to the fence, the music starts playing again and keeps looping forever. Is there any fix to this?
