Hi all, thanks for taking the time to read and respond. I have been using my onboard realtek audio on my EVGA x58 motherboard using PC speakers without a problem. However, I have recently moved my PC into the home theater. The digital optical out from my motherboard only supports 2 channel...which is lame. So my question is this: Which PCI soundcards support 5.1 through it's digital optical out? Thanks!
