Yes, I'm aware of that.
However, XAudio can load an OGG file and play it on a channel, which is what I did with another test to get around the "cannot play OGGs as music without the codec" issue (which, on a side note, is why I was suggesting using something like SDL_mixer - it seems weird you can play OGGs as sound effects but not as music!). That was stored as an external file - it spawned this topic as a result. It is trying to do the same thing but with the OGG file as a binary resource that's failing.
