I really need help with this. I recently bought Oblivion GOTY Deluxe Edition on Steam. The first time I launched the game it ran perfectly. The next day, I launched it and there was no sound at all. No music, no sound effects, no dialogue. I have tried reinstalling but nothing. When I look at the audio options in the main menu, all of the sliders are turned down. Even if I turn them up, nothing happens. I am running Windows 8, if that helps.
