No engine sounds

Im converting ArmA 2 samples vehicles to ArmA 3 as Addon. I made almost evrything, 99% work done. Last thing - engine sound. After turning on engine, sound of engine dissapear, i have wheels, rocks on road, animated turret, shoots, but NO engine...Any ideas? Im using base config of ArmA 3 vehicles.

1) did you make sure to use the X simulation classes?

2) did out use the A3 sounds? if you use the A2/OA sounds/class sounds, you probably have to update their class names/adjust to the new schema

1) No, and im not going at this moment. I hope its possible to do it witohut X ...

2) A3 Sounds.

You need X simulation for sounds.. Or wait till BI fixes it:
