I have a dedicated music server from which I get S/PDIF output to my DAC. Optical output from the motherboard produces junk, so I use a Sound Blaster Audigy RX 7.1. With Direct Sound enabled, my system sounds great. Unfortunately, the card sometimes disables Direct Sound for reasons unknown, and it's a pain to check periodically. I'm hoping either to learn some way to lock on Direct Sound, perhaps through the registry, or replace the card. Obviously, I have no use for any card's onboard DAC or music processing, but I'd pay what I need for a card that produces the best PCM stereo output and doesn't require attention.
