Correct way to use game sounds

[PELHAM 10]

Is there a way to use the sounds that are already in game? I know how to define custom sounds and music in the description.ext but there does not seem to be any info on using BIS sounds. I have tried several methods but no luck.

eg the C130 internal sound is this but how would you use it to give the static C130 the same sound?

class EngineHighIn {
frequency = 1;
sound[] = {"ca\sounds\Air\C130\int_engine_hi", 1, 1};
volume = "(1-camPos)*(engineOn*(rpm factor[0.55, 1.0]))";
