I started with Realtek Audio on board sound card on my MSI MB. Even with ASIO drivers keeping windows out of it, this card always seems to sample everything to 48K (my Yamaha DSP A2 says as much). So I tried an Audigy 2 I've got. It samples at 48K or 96K and as my amp can't use 96K the latter ain't much use. Would a card that leaves CD plaback at 44.1K help matters much, which one, and is it worth it when I've got to have my old DVD player in the rack on stand by and it does a pretty good job with CDs?
