Wel i don’t use DSD Files.
It happens with flac’s and wav’s. I did try the Picoplayer option from Florent. Thanks for your response. It works perfect with no pops and clicks. But Volumio sounds better to me. Cleaner, more details an lively.
To bad…
you will find your dsd dop 
I now try out ROON. Looks and sounds very good.
No pops
On your rPi???/
