Edward,

Thank you for replying.

I'm not sure I can count on the hardware vendor to care that 
enthusiastically about Linux support. They did provide Linux drivers for 
the onboard sound and network devices on their CD-ROM. But I get the 
feeling that was done more in the spirit of the fact that applicable 
Linux drivers were available anyway. They certainly don't seem to be 
very up to date or well documented.

What's throwing me right now is that there seems to be a certain random 
quality to the way my sound devices are handled. I've disconnected my 
USB sound device for now in hopes of cutting down confusion.

However, I still have two devices listed in my Gnome Volume Control:
HDA Intel (Alsa mixer)
Realtek ALC882 (OSS mixer)

Before, I was able to record my voice in Audacity. Now I can't. Before, 
Audacity had two sound devices for me to choose from:
/dev/dsp
/dev/dsp1

Now it only has /dev/dsp/ and I can't record anything with it.

I've discovered a GUI for ALSA Mixer, which says I have:
Card: HDA Intel
Chip: Realtek ALC882

Which leads me to believe that they are the same thing, but being 
treated differently by the OS.

How can I cut the confusion down here? Is there anyway I can wipe the 
slate clean and do a fresh install of the drivers? Clearly I want to be 
using one set of drivers for the one card I have.

By the way, if it helps, here is some information I found through the 
ALSA Mixer GUI:
