Hello,
I recently did some major upgrades and finally got all items working.  However, when I start engines, and throttle up,  I get the most annoying popping sound from my speakers. It appears to only be the engine sound. I am using a SoundBlaster AudioPCI card and Thrustmaster attack throttle system.
What could be causing this?  It happens in
AH and WB, but not FS2K.  
Thanks,
Texman
Flying but annoyed
