If you don't CC maintainers the chances are your mails just won't get
seen...

You should change DAPM so that it understands what your control is
doing, possibly by using custom accessors though it seems like something
in the vein of the invert flag ought to do the trick.  You don't want to
actually use the invert flag since increasing values do mean increasing
volume but something along those lines.  Possibly doing it by parsing
the TLV for a mute value at probe time might make sense?
