Despite its name "HDSPe", the MADI FX is a new card with a similar but different design requiring new userspace tools.
These tools don't exist, yet, but to facilitate their development, expose a preliminary userspace API. Note that the stable bits are always enabled while the volatile parts require CONFIG_SND_MADIFX_BROKEN to be set.
