Since no one seems to have the same problem or know a solution, I have
to find something that would work for now.

What I did is move /usr/bin/mplayer to /usr/bin/mplayer.binary and the
create a small one line bash script that did:

mplayer.binary -ao oss "$@"

However, if anyone know how to really fix this, I would really
appreciate an hint or a solution?
