3D sound & child objects

[FlyingWren]

Phenomenologically, 3D-sound played from objects loaded with viz.add() seem to be generated from the correct position. However, 3D-sound playback from objects loaded with viz.getchild() seem to be at the wrong position. For example,


objRoom = viz.add('Room.wrl')
objVent = objRoom.getchild('obj_Vent')

# start sound playing
objVent.playsound('air-vent.wav', viz.LOOP)


The 'air-vent' wave file seems to be playing at the position of the "Room" object, not the actual "Vent" subobject.
