I recently acquired an ATI HD2600XP card (PCI-e) and it seems to work very well outputting HDTV. However, it's also supposed to output sound over HDMI (actually via one of the DVI outputs and ATI's DVI->HDMI adapter) but I can't get the sound to work. I've installed the HDMI sound driver (multiple times) but the device doesn't show up in device manager. I also installed a Microsoft patch that handles HDMI sound bit still no workie. Anyone else running one of these cards and have the sound working? I'm running XP Pro/SP2 and the latest ATI drivers (7.10). I can get sound out of the sound card but I'd really like to get the HDMI sound to work.
