Hi,I have FSX and Acceleration.Stange problem with sound recuring after reinstalling FSX 3 times.There is a lot of parasites sounds and behind it the normal voice and engine noise.The problem disappear at higher altitude (10'000 ft) ???After 10-20 minutes of flying, it leads to CTD. I suspect there is something wrongwith the sound card even thought I don't have any problem with other applications.Thanks for tips and helpGeezee

NO it isn't your soundcard!!The sound is just an symptom that something is wrong, its just the easiest thing to wipe out for an overloaded system.What is causing the troubles? My guess is as good as yours..................................
