Associating a sound PBO to World?

[loosebruce 10]

Hey all,

I have a major problem that I have so far been unable to solve.

The problem is that I have two wonderful Ambient sound addons I have made which are both in seperate .pbo's.

However they are different in the sense that one of them is for a desert map and the other one is for a european/forest map.

Both PBO's require the use of "CASounds.pbo" in their configs but this presents a problem in the sense that only one of my sound pbo's will work and the other will not do anything.

e.g.

Desert_sound.pbo will play on both Chernarus and Isla_duala.

Whilst Forest_sound.pbo will not play at all even if its loaded into ArmA2.

============================================

Is there anyway I can get one pbo to activate on the correct world whilst the other one activates on its world?

I have a feeling "Class Defaultworld ;" might be able to help me out?

So does anyone have a workaround or an idea?

Cheers,
