while i'm deleting your rationale for the above, i'd like
disagree fundumentally with this.

play.gain is the traditional way the "sun audio" interface has
worked, so any other tool that thought this was a master volume
(which it has been, until recently) has to be updated, whether
it is a C program or a script.

that's not particularly nice for the end users, so i would like
to at least restore the original functionality if there is one
vchan only, if not more generally.

thanks.
