If you have the SPDIF Out box checked, then you will get no sound at all. Your selections should be:
Audio Channel: 6 channels
Sample rate: doesn't matter
Analog out: 5.1 speakers
SPDIF Out: NOT checked
Virtual speaker and Pro Logic IIx are a preference thing, and you will just have to play with those to see if they suit your tastes.
Also make sure Hi-Fi mode is not on... it may force stereo. I don't remember, because I'm using the standard C-Media interface instead of ASUS' proprietary stuff. So, I don't have Hi-Fi mode or SVN.
Putting the card in 4, 5.1, 7.1, etc, will send music to all the speakers. I'm listening to it that way now. You may prefer 2- or 4- channel sound for music though. It depends on the quality of your center, spacing of the speakers, etc. Try different modes and decide what suits you best. I find 4-channel mode best for my music needs.
