Hello,
I finally have got three zones from my Audigy.
You need the drivers from here:

Once you have the full set, uninstall those lovely creative drivers, and install these.
Once alll the reboots have happened, its time to setup winamp.
If you go to the output section of the settings, and choose to configure the waveOut Output.
Under the Device drop down, you will see these (and maybe others):
kX Wave SB0090 10k2 [b800] 0/1
kX Wave SB0090 10k2 [b800] 4/5
kX Wave SB0090 10k2 [b800] 6/7
kX Wave SB0090 10k2 [b800] 8/9
The numbers might be different depending on the card you are using.
Each one of those lines represents a different output on the back of your card:
0/1 : all channel - NOT USED IN THIS SETUP
4/5 : front channels
6/7 : rear channels
8/9 : centre / sub
And by setting each instance of winamp to one of the above you can get three outputs from one card.
If it is not working, it will be down to the DSP router. I will post help for that next.
Simon.
