I've done quite a bit of googling and could not find anyone else who had my hardware and particular problem.
Background Information: My SB Live 5.1 works, but I get this really annoying background/static noise from the center speaker. The noise is only generated when sources generate a sound event (i have no noise from this speaker/channel when no application is generating sound). I had this problem using the emu10k1 sourceforge drivers and kernel 2.4.x, so I upgraded to kernel 2.6.3 to see if using ALSA would solve the issue.
The upgrade did not.
I played with the numerous sliders in alsamixer, but none could alleviate the noise. The noise only goes away when I physically unplug the line coming out of digital output on the card.
From my searches on this forum, it seems no one else has had this problem. Anyone have any ideas on what is wrong?
Actually, I can't get any sound EXCEPT for this noise from the center speaker. I suppose the next question to ask is how to enable output from the center speaker, assuming I can get the noise to go away.
here's my lspci output:

Maybe this is truly a hardware issue and my card is funky?
Thank you in advance.
