Whenever I load a custom aircraft (FFA320, B767, Magknight B789 or Jardesign A330), I have huge soundbugs. Sound is laggy and distorted, even on sounds outside the sim (music, for example). As soon as I pick a default aircraft, sound is ok again.
I tried reinstalling Audio Drivers, check different output devices, reinstalled X-Plane, all to no avail.
Any help is appreciated.
