No, both SDL and SDL_mixer know about 5.1 and 4.0 sound, and the
Alsa interpretation of 5.1 channel order is built in to SDL as well as

It is.  And it is also supported for .ogg, .mp3, .wav, and mod files 
(though the
.mp3 and mod support is faked by copying channels).  And all the support
assumes Alsa channel order (except for 6 channel .ogg and .wav files which
are played in 5.1).
