You say "these controls" but it seems like only "Playback Volume" has
a problem?  My first suggestion would be to define "Analog" or
"Analogue" as a prefix in ControlNames and then use that, that would
avoid confusing applications while still fittig in with the naming
convention.

It may not be policy that someone wants to tweak at runtime on your
board but it almost certainly will be on someone's board.
