let me put it this way...
if elbox can't make a SB LiVE/Audigy driver which has open source drivers available with all documentation of the dsp, mixer, midi and so on (including the managers/SoundFont/Surround Sound etc) they will certainly not be able to make any kind of driver for the Terratec Auron.
and since the reason why they can't make a SB LiVE driver therefore must be a hardware fault/bug/limitation of the mediator the same limitations will most likely stop any driver for something like the Auron too.
:-x :-(
