Game Crashes and flashing screens

[DzrtFox]

Yes, sounds were working perfectly right up until the crash. I've noticed the crash happens on both my turns and the AI's. I don't think that there is anything really intense happening sound-wise when it happens, it seems like it will happen at some random point during the turn but it does seem to happen always like right when a vehicle starts moving. I will try to see if I can cause the error again and I'll try to notice what is going on when it happens...
