When I try to communicate with ATC, or when the lesson/training flight begin
the voices sound fine for about the 1st 3 sec then the start getting slower
and slower and then it starts snipping 1/4 seconds from the speech. I've
tried switching sound on and off in the sim, it doesnt work,

Pc Specs:
Athlon 1300Mhz
GeForce 2 MX
80Gb HD
Onboard Sound
Latest Drivers for all hardware.

Any Help Would be Appreciated.
Tnx,
AVi
