Don't know exactly about the emu10k1 thing. That may be OSS getting
loaded somehow? All of the Alsa modules start with snd-XXYY. Here's
what mine looks like:

flash mark $ lsmod

Since you don't have that sort of stuff it says Alsa isn't loaded.

Look at dmesg carefully and see what info it gives you. Possibly you
are not loading the right driver, or possibly the right driver cannot
load because OSS is loaded and has taken over the hardware.

Getting rid of OSS is beyond my skillset, although there is some info
on the PlanetCCRMA site. It may apply since you seem to be running a
2.4 kerenl, although it's for Redhat and you're running Debian...

Good luck,
Mark

P.S. - Any girl who makes music and brews beer is perfectly OK with me! ;-)
