Hello folks!!!
I have an unusual trouble with the sound, after some minutes (where I don't open other program or don't do other actions) the sounds like switches, seat bealts or no smok, or APU, disappear!!!  >:(
I tried reloading the aircraft but nothing!!!!
To have again the sounds, I have to reboot FSX and load the aircraft twice!!!! But after some minutes... one more time the sounds disappear!!!  :'(
Anybody have this issue????!!!!
How I can resolve this problem????
And why the CS with 4 s.p. wasn't able to fix this boring trouble????  :-? (sorry CaptainSim!)
