◆ RegisterBusVolumeCallback()

AKRESULT __cdecl AK::SoundEngine::RegisterBusVolumeCallback ( AkUniqueID  in_busID,
AkBusCallbackFunc  in_pfnCallback 

Registers a callback to allow the game to modify or override the volume to be applied at the output of an audio bus. The callback must be registered once per bus ID. Call with in_pfnCallback = NULL to unregister.

Note: The bus in_busID needs to be a mixing bus.
Note: Beware when using this callback on the Master Audio Bus: since the output of this bus is not a bus, but is instead a system end-point, AkSpeakerVolumeMatrixCallbackInfo::pMixerContext will be NULL. You cannot modify panning at the output of the Master Audio Bus.
