So the Libraries and Apps are installed.

OSS doesn't have any packages containing libs like ALSA. To use it, you
only need the drivers from the kernel-image package. So there is
nothing to uninstall, except maybe for output plugins of your
applications.

There is no need to do that. First, if you use Kernel 2.6, you must make
the changes to /etc/modprobe.d, not /etc/modutils. Second, the debian
package management and alsaconf should take care of that. On my system
I have:
andreas@sirius:~$ cat /etc/modprobe.d/alsa-base
install snd-pcm /sbin/modprobe --ignore-install snd-pcm
&& /sbin/modprobe snd-pcm-oss
install snd-mixer /sbin/modprobe --ignore-install snd-mixer
&& /sbin/modprobe snd-mixer-oss
install snd-seq /sbin/modprobe --ignore-install snd-seq
&& /sbin/modprobe snd-seq-oss
andreas@sirius:~$ cat /etc/modprobe.d/sound
alias snd-card-0 snd-emu10k1
alias sound-slot-0 snd-emu10k1
The only thing I had to do was to add snd-emu10k1 to /etc/modules,
because without it the init skript for setting the default volume
failed.

That probably means that the OSS driver module is loaded before the alsa
module is loaded. That way ALSA can't work. You need to make sure that
the OSS driver is not loaded. Check /etc/modules for the driver,
and /etc/modprobe.d/* for entries like
alias sound-slot-0 driver
where driver does /not/ begin with snd.

That will only reload the volume settings.
