I've got a Asus K8V Deluxe and a set of Logitech Z680s. When I bought my rig I opted against getting an additional sound card since my board features 6 channel output, and the card I was looking at featured DTS & Dolby Digital which would conflict (even if only in terms of money wasted) with the same system built into the speaker setup.
Anyway, I've been running off coaxial since I got it (winces at sharp intake of breath from audiophiles) and only recently realised that I've been running off Stereo X 2 rather than true surround, something Coaxial doesn't seem to support. We moved recently and I haven't been able to find either instruction manual so I'm coming to you guys for help. The Z680s offer Coaxial and Optical on the digital side, as well as 6 Channel Direct connections, but can only see the coaxial connection on the motherboard (as well as what looks to be a closed optical connection). I'd like to get the 6 channel direct connection working since I have the cables but would someone mind walking me through the options open to me....
Cheers
