Right - this is not the modern Alsa driver. This is an older driver
created by Creative Labs themselves. It's hosted at Sourceforge.net,
but it's not the right driver for what you want to do. I think it's
this one:

http://sourceforge.net/projects/emu10k1/

It has loaded and taken over the hardware which would then stop Alsa
from loadign the snd-emu10k1 driver. We need to determine how it is
getting loaded. It appears from your first post that your modules.conf
file looks about right. I don't know what else could be loading this
driver, but something is. Can you figure out what?

I really think this isn't an 'Alsa' problem per se, but more that this
other driver is getting loaded and oyu don't want it to.

Does Debian have an extra places to load modules at boot time? Gentoo
has an extra place, /etc/modules.autoload.d/kernel-2.4, where you can
place instructions for this specific kernel, and one for 2.5, and
another for 2.6. Possibly Debian has something extra like this and
that's where the file is gettign loaded?

I misspoke. Clearly Alsa is at least partially loaded, but the sound
card driver is not loaded so Alsa probably thinks it's just
responsible for MIDI or something...

That's a pretty big change. This is solvable. Let's try and find
what's loadign this driver.
