libvorbis uses lots and lots of floating point, perhaps your ARM 
processor can't decode the ogg fast enough to play it in real time?

You should try libtremor, which is a replacement vorbis library that 
uses only integer math. I think it's a drop-in replacement, so it should 
work with SDL_mixer.
