I have always hated that the using an Amp for a turntable would show up in the “Rooms” even though it is being used as a source and not a speaker — My way around this was to name it “zSOURCE-TURNTABLE” so it would drop to the bottom of the list of rooms to so all the speakers would show from top down and its name would also show that it is a source

Prior to this new terrible App redesign - when I would choose “Line-In” as the music source it would at least show that it was playing the turntable — With new App it will not let me label the line in as Turntable — so playing Turntable only shows that it is playing “Line-in”
