This is the machine that you started with, except that the external
sound card and hard drive were replaced, correct?  Did you remember to
blacklist the driver for the motherboard sound chip?  The blacklist goes
when the hard drive goes!  Then shutdown and reboot.  Then run
"dpkg-reconfigure -plow alsa-base alsa-utils" for good measure,
shutdown and reboot again, and see what you've got.  I think you may
be looking at that integrated sound chip that you can't connect to.
Of course, if you were unlucky enough to pick a sound card that
requires the same driver as the motherboard sound chip, you're hosed.
Issue "lsmod|grep snd" and post the output again.

Also, GNOME sound configuration is primarily for the benefit of
GNOME system sounds, such as startup, shutdown, opening and closing
window sounds, etc.  Applications that run in GNOME can produce
sound even without GNOME sound configuration.  The best test for
basic sound is to use the aplay utility on a .wav file, as documented
on my web site.

Sounds like either the original sound card was bad or there was
a hardware conflict between it and the rest of the system.

If the BIOS setup program has a way to disable it, then disable it there.
Otherwise, about all you can do is blacklist the driver.
