That's true, the mixers I did always output SAMPLE_FMT_S32 anyway. The
soundcard drivers I did in TuComposer were responsible to convert
SAMPLE_FMT_S32 to the target soundcard format.
SAMPLE_FMT_SEQUENCER would be target if we do a conversion between
different mod files instead of wanting PCM output.
