When I minimize or Alt-Tab out of TW3K, the game sounds should not play while the game is minimized, since I have unchecked "Sound in Background". However, sound still plays when I minimize the game.
Steps to recreate:
1. Go into game settings.
2. Go to audio tab
3. Uncheck "Sound in Background"
4. Confirm settings
5. Minimize game
6. It doesn't work, game sounds are still playing while game is in background.
