Thank you for your assistance, Chris.  I appreciate it.

Here are a couple of details which I omitted:

* I disabled the VIA 8235 in the BIOS.  (I certainly don't want it but do
  I need its AC97 stuff?)
* The SB Live is sharing an IRQ.  (Scant details below.)

The lack of a large number of complaints about the board lead me to
believe it's simply a configuration problem on my system.  Virtually all
of the solutions offered for a lack of sound involve unmuting the
outputs.  I've tried every mixer I can find on my system, now including
gnome-alsa-mixer, gnome-volume-control, kmix, and alsa-mixer (this one as
user and as root).

I spent about four more hours searching with Google and probably an
additional three hours reconfiguring, recompiling, rebooting, and/or
remixing.  I'm tired of it.

After various and sundry and random attempts to fix the problem, I find
that when I rebuild ALSA, the number of modules loaded has decreased
greatly.  In my fit of hacking, I don't know what I've done differently.

Here's what I discovered: If I build the kernel's (OSS?) emu10k1 module, I
get sound from my system.  I'd like to get ALSA working and it seems like
giving up just to use the kernel's code.  I'm going to leave it until the 
weekend when my frustration level is back to normal.

No apologies necessary.

I didn't write down the exact wording, but I got the numbers which go
something like this when ALSA is loading:

  Found device at PCI address 00:0c.0. Using IRQ 5 for 00:0c.0
  Sharing IRQ 5 with 00:10.2

PCI 00:10.2 is a VT6202, identified as the second of three USB 2.0
controllers. I don't have any USB devices.  I didn't think to try
disabling one or more controllers in the BIOS.

Yes.  It displays the name of the file being played and the pauses for
what seems to be the appropriate amount of time to play the WAV file on
the output device.  Then, I get my command prompt back.

None.  Nothing generates any error messages that I can find, although I've
only looked at the console (for "play") and ~/.gnome-errors (for
everything else).

I'll attempt that, also.
