Hybrid-DSD is a MP4 container file
(<filename>*.m4a</filename>) which contains both ALAC and
DSD data. It is disabled by default, and works only if you
explicitly enable it. Without this plugin, the ALAC parts
gets handled by the <link linkend="ffmpeg_decoder">FFmpeg
decoder plugin</link>.

plugin should be enabled only if you have a bit-perfect
playback path to a DSD-capable DAC; for everybody else,
playing back the ALAC copy of the file is better.
