Yes, there are no OSS-compatibility module. It should have these as
well at least: snd-pcm-oss snd-mixer-oss snd-rawmidi. You could try
manually modprobing them, but better put them in your alsa-modules
configuration under /etc/modutils/ like:

  alias sound-slot-0 snd-card-0
  alias sound-service-0-0 snd-mixer-oss
  alias sound-service-0-1 snd-seq-oss
  alias sound-service-0-3 snd-pcm-oss
  alias sound-service-0-8 snd-seq-oss
  alias sound-service-0-12 snd-pcm-oss

then run "update-modutils"

This is only using alsa itself. With the oss-modules loaded, OSS apps
should work as well.

See above, you seem to miss the OSS-compatibility modules.  Are you
using ALSA 0.5 or 0.9? If 0.9 you could try my unofficial 0.35 Debian
packages on footils.org. It's still test17, I'll put up
the latest version the next days.

ciao,
