Ok, a little foggy when I was shopping and getting peeved that no one chose that excellent apu. Well I remember now why I got my ILSR, or one of the reasons. Problem is I don't have digital speakers I have the old Klipsch promedia 2.1's so I am going through the crappy Realtek DAC to get my sound. Is that hurting my benchmarks? Probably/Hopefully not. Do most users have digital input speakers for their PC's? I doubt it so they should still be aware of the sound quality issue. /shrug
Here is a pretty good link for a more concise answer. View the diagram a few posts down.

Also, looknig at Nvidia's site now... There are only 3 boards certified to Soundstorm... The Abit, the MSI and another which I forget. When I was shopping there were "none" listed as the MSI was brand new.
When I was shopping this motivated me to find someone, anyone, using the Nforce2 APU.
Sweet article from Tom on sound and games If nothing else check out the benchmarks!!!!
And wrongly.... I used this table early on in trying to find MY APU!!!
Early table of Nforce2 boards and their sound chips Very close in time to the article on APU's vs. discrete sound cards.
Well that was a mouthful to say Yep, I was wrong about no one using the APU. Now to figure out why I don't have any soundforce software interface on my ILSR
