Ok. I did a bit more research into the Vista Drivers question, and I found that C-Media actually has a beta driver for the CMI8788 chipset that is already available. This driver is missing DDL (Dolby Digital Live) and DTS surround encoding functionality on the digital output, but everything else works. This is what Sondigo recommends using for their Inferno for the next few weeks until C-Media's Vista drivers become available. From my own testing, it appears that the Razer Barracuda AC-1 has complete functionality under C-Media's CMI8788 drivers, so I suspect that you could limp along with that solution until Razer's own Vista drivers and control panel become available.
