I would like to be able to set the volume of certain rooms (that have an amp with external volume control) to a higher (or lower) initial volume. In the living room I have to either turn my external amp way up when selecting Sonos as input (and remember!!! to turn it down when switching input so the tv input don't blow the speakers) or when grouping rooms turn that one room all the way up in Sonos). I like the rooms to be the same volume across inside Sonos so they all reflect the actually volume level.
So basically adjusting the delta volume per device when set to variable line out.
I have not found a way to achieve this yet.
