Description Of Issue

Roon’s volume control behaves strangely for my Dragonfly DAC when it’s connected to a Roon Remote: When the volume control is set to “Device Volume”, it doesn’t actually change the device volume but instead seems to do DSP volume control.

Are you using “Exclusive Mode” for the DragonFly zone? “Device Volume” will only change the hardware volume when “Exclusive Mode” is enabled.
