I have played this game as well and it is quite enjoyable. Worth noting is that is uses Novalogic's own 3D sound engine which only works correctly with headphones or 2 speakers. Basically it uses a set of frequency filtering algorithms to position sound around the listener, but it is behind HRTF phase manipulation used by hardware based solutions such as Creative, Sensaura, Aureal and Qsound."

I have audio programs that will produce the sort of 3-D effect over two speakers experienced in Comanche 4. The effect isn't that unusual.:)
