What about running the oss application through aoss wrapper?
apt-get install -q alsa-oss
aoss mp3blaster

Ok I am doing the same here but some times we don't have
newer versions of these apps wich are alsa capable!

The easiest way is to use aoss wrapper (not for speechsynthesis!!).
Another solution is to set LD_PRELOAD variable in your ~/.profile
or ~/.bashrc. Look at the aoss skript!.
This should work for all apps.
