The only time I hear the engine sound is in a recorded plane. The voice in the lessons sounds perfect (no drop outs) as well but I don't hear any plane sounds during the lessons either. I tried to turn off every feature in the Audigy but it made no difference. I DL'd the newest DirectX and Sound Blaster Drivers just to be sure. Still no change.

With the Volume Cranked ALL THE WAY UP I hear the engine sounds of my plane under the static. If I also fly with a recorded plane, that plane's engine is at normal volume. As the recorded plane flys around me the sound moves to the appropriate speakers (behind me, to the right, etc...).

I am still leaning toward the problem being with the 3D sound. I think that the Audigy believes the sound from the plane is very far away from me so it plays it at a very low volume. However, it never gets closer to me regardless of what I do.

Does FSOne use EAX or anything like that?? I have got to think it does since the sound from the recorded planes move around my speakers. Although the music goes from nornal to very quiet ever few seconds I don't think the sound or the music every actually "cut off".
