I have an MSI Neo FISR2 and it has spots on the mobo for Front L/R speakers, Rear L/R speakers, and center speaker, so my Klipsch 5.1 speakers hook right up. I'm considering a P4 system with the ICH5 southbridge (6 channel codec), specially the p4p800-vm mATX board. It says it supports 6 channel audio but I only see sound in, sound out, and mic. Would I have to have a SPDIF connection to an audio receiver to get it to work? Thanks.
