I have also noticed on my previous board (Asus A8N32-Sli deluxe) that the sound was below average quality, but everything else was superb.
Now I have the same board being discussed here and I haven't had any of the stated problems. I'm glad you finally got it working, but I would still contact Asus if I were you, as my sound is excellent going through a 5.1 surround system.
