DSD files do not play when crossfeed or EQs are enabled

[thefitz]

The DSP functions including EQ, Crossfeed, Replaygain, etc only operate on PCM format. If you try to play a DSF/DFF file it will be converted on-the-fly to PCM by MPD before being processed by the DSP component.

Understood - thank you! The error message made it look like a bug, but it makes sense that the conversion is "hogging" the DSP.
