I figured it out...
When I had the system apart to install the Audigy and the Hard Drive, I
decided to go ahead and re-locate my sub-woofer during the drive formatting.
It was too boring to watch:)
The new Ultra 5.1 sub is MUCH bigger than the original Klipsch 5.1 sub, and
it didn't really fit well in it's old location.
So I moved it, which required me to plug it into a different outlet.
In the old configuration the computer and the sub were plugged into the same
circuit. In the new configuration the sub is on a different circuit. This
appears to have created some sort of ground-loop in the system.
I used a heavy duty extension cord to plug the Sub back into it's original
location, and the hum (99% of it at least) went away.
Again, after the system boots up and windows installs the drivers, the last
1% goes away.
I can only surmise that it's because when the Audigy drivers are loaded, the
sound output jacks are enabled and the computer and sub are getting a common
ground through the audio connector patch cable.
