Yes, both the sound card and the onboard chip. Best I can make out the
snd_hda_intel is the kernel module that supports the onboard (Gigabyte)
Intel 38201I chip.

It seems that I simply need to disable audio support in BIOS. Can I do
that without disabling sound card audio as well?

Perhaps the reason is that in this box I originally had a Sound Blaster
Live card, and simply switched cards prior to reinstalling debian. What
is best way to get the right modules (emu20k1 and emu20k2) loaded
instead of the emu10k1? In /proc/modules, it is the emu10k1 that is
listed. 

How would I correct this?
    
    # modprobe -r emu10k1
    # modprobe emu20k1
    # modprobe emu20k2

I assume I need to restart the audio system. With alsa-utils?

    # /etc/init.d/alsa-utils restart

But these are not permanent. To get emu20k* to load at boot time, do I
add it to /etc/modules? If so, how do I keep the emu10k1 from not
automatically loading?

/etc/modeprobe.d/alsa-base.conf seems to be a place in which modules are
added and subtracted. I'm not sure if this file can be edited, and
there's no man page for the syntax. In this file is the line:

  install snd-emu10k1 ...

Can I just replace this line with two lines like this:

  install snd-emu20k1 /sbin/modprobe --ignore-install snd-emu20k1 && { /sbin/modprobe --quiet snd-emu20k1-synth ; : ; }
  install snd-emu20k2 /sbin/modprobe --ignore-install snd-emu20k2 && { /sbin/modprobe --quiet snd-emu20k2-synth ; : ; }

and add to prevent emu10k1 from loading:
      
  options snd-emu10k1 index=-2

I suspect not because the lines in this file repond to sound card capabilities.
