Drivers may work for WIN9X, thanks to Ilam Mougy who uploaded as generic Turtle Beach driver. Your TBS400-3355-01 with the Vortex AU8820 chipset is a Montego card. the TB website is no help at all since they don't reference the Vortex chipset anywhere. I wasted 10 hours looking for model specific, but thank God for Ilam.
