Bei gewissen GAV-Flieger ( neuen ) von Carenado kann man die Lautsärke der Motoren im X-Plane Menue "Ton " nicht varieren.

Hier die Lösung und es funkt!


The Seneca, Bonanza A36, and Centurion all have their engine volume controls as 3D knobs in the cockpit. (Try the volume knob on the audio panel.)

The Pitts' volume knob is the "Radio" breaker. If you hover your mouse over the breaker labeled "7", you should get the old +/- manipulator icons. Click and drag down to make the engine sound softer.
