in this mode, what happens on re-opens?

would nas mixers track changes made by non-nas mixers?

just like i believe erik, i guess i'll have to believe you.  :-)
i myself don't think i'd want this.  but maybe i'd find a use!

so, here's the mode that i think i want:
    - i don't particularly care whether nas sets defaults on startup
	or not.  that's a one-time initialization, and i could do it
	in the script that starts nas just as well.
    - i want nas to always use *and report* the current mixer settings.
	if another app uses and adjusts the mixer, i want nas to notice
	that, so that clients can see that it's happened.

it's entirely possible that what you've expressed as a list should
really be a combination of separate booleans:
    a) init to default values at startup, or not.
    b) reset to default NAS settings on every open, or not.
    c) reset to last NAS settings on every open, or not.
    d) track other app's changes to the mixer, or not.

i'd just turn on 'd'.  i think jon would turn on 'a' and 'b', and
i think erik would turn on 'a' and 'c'.  but perhaps this misses
something that you two have been mentioning that i didn't
understand.
