Just yesterday I encountered a rather strange thing: Though I didn’t change the level of the output of the DS DAC (set roughly at 60-65), the output volume went dramatically down. I have this issue when playing via USB and also CDs (via PWT).
Now I have to turn up the volume to almost 100 to get the same volume. This kind of strips me from attenuation reserve…
EDIT: I’ve already switched off and restarted the DS DAC; still the same. Ev’tually re-install Roon?
