In reply to:
Your assumption is correct; if you connect to your receiver using the digital outs, you are bypassing the output DACs in the Audigy. Thus, it doesn't make any difference if you do swap front/rear. In other words, that option is only useful for people who do not use PCM (Pulse Code Modulation -- Stereo SPDI/F out).
I don't fully understand your question for the last part. I stated that all of the DSP circuitry should be bypassed (which can be accomplished by right clicking all but the left most and the right most parts and selecting bypass. Currently I am using creative drivers (for EAX HD Support) so I cannot check, but in the DSP Map, I used to disable everything and still get the same level output. I may re-install those drivers one of these days, however, to be of more assistance.
Also to point to the thread that you are referring to, make sure "View Threaded" is enabled (by clicking the upper left icon that says threaded and find the post. Once you have the url, do [u

By the way... I am glad that the drivers I suggested had a noticable sound quality improvement.
