You can enable it by adding to the ALSA section in mpd.conf:

 dsd_usb "yes"

Obviously, it is important to have bit-perfect 24 bit playback on the
wire.  A conversion will be destructive in any case.  dmix must be
disabled.

It's experimental so we don't now if it works or needs works. Please
provide any feedback!
