Very much so; thank you!

MikMod keeps a bunch of global state, such as sample rate of the output
buffer. SDL_sound sets this, and no doubt so will SDL_mixer. If they don't
match, things will break. There's no good way to fix this short of making
sure everything matches and praying, or using one or the other.

When I rewrite SDL_mixer, it will use SDL_sound as a backend for all
decoding, which will fix this, but I've been promising this forever.
