Denon receivers and absolute volume

Hi all,

Does anyone with a Denon receiver know how to make Roomie display volume on an absolute 0-100 scale? I have this setting changed on two different Denon receivers to show 0-100 instead of relative db, and it does show 0-100 on the Denon’s screen and OSD, but not Roomie’s UI - still showing “-35.5db” instead of “55”.

I can confirm on an Onkyo when you change this setting Roomie reflects it immediately. Could this be a Denon code set issue? Thank you!
