Got the PCI to PCIE adapter today and put 2 AMD video cards in my pc and both 3D and HD Audio bitstream finally works as desired. Too bad there is no way to lock down the PCI adapter card so it is just hanging loose. Also video through the PCIE adapter is lagging so it is strictly for audio bitstream only. BTW bitstream with Nvidia cards simply won't work under Vista. Wish I had read it earlier so I don't have to waste time trying.
