[SDL] problems loading ogg and wav music.

[James Barrett]

I tried loading my ogg music file along with my other sound effects.
The program no longer crashes, but the music does not play. Sound
effects play just fine. Is there some reason why SDL_mixer will play
one ogg file and not  another? Am I doing something wrong or is there
a bug in SDL_mixer?
