I run the speaker test from the Creative Labs mixer and it only produces sound on the front left and right speakers.
For the digital coax signal, that's still correct. The Audigy 2 itself does NOT do Dolby Digital or DTS
ENcoding. It can DEcode 5.1, but the soundclips for the speaker test are not 5.1 encoded. That's why the 5.1 sound test using digital coax only outputs stereo left/right.
Exactly, s/pdif passthrough using the digital output will ONLY output the source in its original format. For instance, if you use s/pdif passthrough to your A/V receiver, your Audigy/2 is no longer doing any of the decoding, its "passed through" to the receiver to do the decoding. For analog sources, chances are it'll be done in vanilla Dolby Surround sound.
The Audigy 2 (not sure about Audigy) will do DD-EX upmixing from an analog/stereo source, but only if you use the analog outputs. The decoding/upmixing is handled by the Audigy 2 itself, and you will get 5.1 speaker output from any source, digital, analog, stereo, etc.
