Sure Peete,
Im no expert at this but I can try to help with the little I understand about RMAA.
First you install RMAA (duh) freeware version
Then you test your Auzen for base comparison, you have instructions on how to test a X-FI here:
SoundBlaster X-Fi Series Testing Methodology
For this X-FI test all you need is a mini-mini cable to do a loopback, line-in to line-out.
Do the "Sound card output (playback) test" 16/44 should be what most want to see, since it is what most of us use.
Then to test the ZERO you have to introduce it to the chain, so your digital out from the Auzen connects to the ZERO (coax or optical), and the ZERO analog out (RCAs line level on the back) connects to the line-in of the Auzen, for recording/analyses.
In this case you need a RCA(x2) to mini cable.
The test will be the "Real-time external audio equipment test"
I'm not sure if the ZERO output level is too low for the RMAA to work, if it is an amp would have to be introduced in the chain, lets hope not.
I am using my motherboard as a transport and my Zero is a WIP atm since I am changing the busted IEC inlet that came with it this week, it caused my ZERO to be disconnected/connect at will or with any little tiny movement, so I cant do this, but I will soon have a X-FI here for transport (I want EAX for gaming) and I will do the same to my not quite as modified ZERO.
If anyone out their wants to add or correct something I said, please do, as I said, I Am a n00b at RMAA testing.
