Okay. This might sound unrelated. But here's what you need to do to solve the problem:
1. Right Click on the Volume icon on your Taskbar, and then go to Playback devices
2. CLick on your Default Device (should be the one you use while playing the game), and click on Properties
3. Go to the Advanced Tab, and change the Default Format to the lowest possible option.
Apply all the Changes.
Then open the game up, and it will work.
