Add On Plane with Sound from default aircraft in background?!?!

[Guest XQ-NUE]

Hello,I got the level d 767 and when cutting off the engines I can listen to the exterior idle sound of the default 737. Even when I install a new soundpackage this sound is always listenable. It is on in every situation besides the sound I installed. Does anyone know how to solve this problem? There is no sound.cfg line nore a sound file in the 767 sound folder with this default sound. I wonder Wehere and Why the LDS767 get's this sound from.Any ideas?

Might be the APU sound? Probably created by a gauge, with the wav file in the main FS SOUND folder?--Tom GibsonCal Classic Propliner Page: http://www.calclassic.comFreeflight Design Shop: http://www.freeflightdesign.comDrop by! ___x_x_(")_x_x___
