I just got a MSI K7N420 Pro system and a set of 4.1 speakers (Logitech Z-560).
I know that to get 2+ channels audio output, I need to use the CNR spf/dif card that came with it (I have it and it's installed) but not matter what I try (I checked a lot of forums and none of the solutions work) I can't get any sound out of the CNR card.
I updated my motherboard BIOS and have the latest nForce drivers.
One of the most annoying thing about the card is that I don't even know if it's installed on my system since I don't know the card's driver name.
What I need mostly is infos about the CNR card since neither nVidia and MSI provide any info other than the card being optional (yes but what if I already have the damn card??!!).
