EAGAIN means that SDL_sound couldn't fully fill your buffer without
blocking for some unreasonable time...it's not really an error, but it
will alert you of a buffer underrun. It's safe to just call Sound_Decode()
again to get more, but this gives you the opportunity to do other

It's possible that the OGG decoder is incorrectly reporting this when it
could fill the buffer more, and since playsound just calls Sound_Decode()
in a loop, we never noticed.
