Wwise SDK 2019.2.15

Sets the Output Bus Volume (direct) to be used for the specified game object. The control value is a number ranging from 0.0f to 1.0f. Output Bus Volumes are stored per listener association, so calling this function will override the default set of listeners. The game object in_emitterObjID will now reference its own set of listeners which will be the same as the old set of listeners, but with the new associated gain. Future changes to the default listener set will not be picked up by this game object unless ResetListenersToDefault() is called.
