Why are higher end cards that have DDL/DTS-C encoder and EAX5.0 not have optical out?! Like the X-Fi Prelude. I'm going nuts here as I though DDL/DTS-C's purpose was to encode unconpressed 5.1 sound so it can fit through optical. WTF and THANKS
BTW: I haven't checked PCIe sound cards because I don't have another slot, just PCI.
