The crash to desktop with no error after random game play is caused by the shadows settings. When you start the game on the menu screen click video options and change your shadows setting to low or just some other setting.
I played about 3 hours and noticed my FPS was kind of low so I went from ultra or high shadows to MEDIUM and the crash started happening every 2 to 10mins. After I set the shadows to LOW it hasn't happened in the last 6 hours. So I'm thinking that was the problem.
Hopefully this will work for some of you. The sound setting crash is not the same as this bug and I have no trouble with any bit or hertz setting in the sound properties. If you are crashing before you get into the game than that is a different bug.
I also have anisotropic and anti-aliasing set to OFF.
