I decided to stop using my Sound Blaster Audigy 2 NX via Toslink and use the SP13000's SPDIF out instead cause LES is more.
The problem was that the volume on the SP13000's SPDIF was controlled by the WAV slider and not the Master VOL slider like the Sound Blaster. (I use the Griffin PowerMate USB to control and Mute my volume and it doesn't have options to map to the wav volume.)
So I did some searching on the internet for an app that synchronized the two. And then I found Frodos MatchVol.exe and he also posted his Source code. I also saw another app that someone made that modified Frodos MatchVol but neither apps matched the two if one was Muted.
Thanks to Frodo, I modified the matchvol.exe to add mute matching also.
Here is the modified exe zipped up:

I haven't started my project yet, but i am about to get a similar setup as yours. I am getting the SP13000 and was thinking about using the audigy 2 NX soundblaster. But before I invest I wanted to know why you decided to go with the onboard sound? How is the audigy 2 NX compared to the onboard sound in terms of quality and features?
If I can get your input before I invest on the audigy or use the onboard sound.

I'm about to sell my Audigy 2 NX here, cause I was having hibernate issues with it etc...
Other than that, when it did work it sounded great, the onboard spdif sounds ok, but not as clean IMO, but it is reliable, works 100% after hibernation.
I have tested many USB soundcards, and actually have one on order now. The new Edirol UA-1EX. If it doesn't work well for my CarPC, I will use it in my future Mini-Mac.
