No audio format on playback panel

Post a screen shot of the Track tab in Audio info. That will display the tags for the file.

Dear Tim, why is it that if I set “DSD over PCM” instead of “DSD Native” I no longer hear any sound from my speakers?
Please see attachment 

Many thanks

First of all DoP is intended for DACs that do not support DSD.
Then I see that in your case it always gets converted to PCM before reaching the DAC... (your DAC does not expose DSD capability, hence MPD converts it to real PCM)

DSD native => PCM gives a real PCM stream the DAC can play
DoP => encapsulates DSD inside PCM frames, which cannot be understood by your DAC... (it sees PCM, but the data inside makes no sense to it)

In the end, leave it playing as DSD Native.

ETA
Can you please scroll to the bottom one of those two audio-info windows so we can see better the DAC info?
