Great job. Congratulations.
The only problem is about ATC comunications. I can listen to engines and environment sounds except radio comunications. I tried to fix audio setup sliders, no way! I can only ear a far and quite voice as coming from neighbor hotel room. My creative SB X-Fi works with 5.1 surround speakers. The low far voice comes from bass speaker, the other 4 do not play any voice. There is a few on FAQ, I tried some How-to but unsuccessfully. With 11.26 audio worked. I think you have to configure "audio surround" for 11.30.
