With the first version of the DS DAC, I controlled the volume with Roon, and it gave me a range of 1 to 100.
With the AirLens, I can set dip switch 6 to enable volume control… but Roon sees it differently, and uses DSP to control it, giving me a range of negative numbers…
My point was that a UI can display things as the designer chooses, and given that Roon has always (for me) displayed an intuitive 1-100 scale, I was wondering how to turn that back on.
