OK. I have an A7N8X-E Deluxe board that has soundstorm. However, I am not hooking up a digital speaker system, I am only using a pair of headphones. So I am wondering, should I continue to use the onboard sound (which I think, since I'm not using digital out is just AC97?) or should I put in my old SB live 5.1 card and disable the onboard sound option?
