Comment 13 for bug 125739

I don't use gnome, so I have no problem with that mouseover stuff, yet I want to use mpg123 on the command line, and it failed with:

  Creating link /home/me/.kde/socket-mymachine.
  can't create mcop directory

So I found this bugreport here.
It seems that mpg123 wants to use arts, but since upgrade to gutsy my system starts oss instead.
Using
  $ mpg123 -o oss foo.mp3

Setting an alias would not work for frontends like cplay, but this workaround does:

  $ echo 'default_driver=oss' >> ~/.libao

See libao.conf (5).
