With a bit more testing I found that simply manually turning off one of
the monitors, and then back on, would trigger the tiny/empty sound icon
for that monitor, while it would still work correctly on the other
monitors.
But restarting plasmashell would correct the problem, without ever
running xrandr --dpi 96 or the like.
So the missing volume icon is pretty clearly a side effect of turning off
kscreen's background service so plasmashell doesn't get notified thru it
of monitors coming and going, but restarting plasmashell restores it to
working.
Meanwhile, I've not seen the previous problems yet, so turning off the
kscreen service really does seem to have cured them, albeit with that
minor side effect. But I can restart plasmashell and fix the missing
icon with a whole lot less hassle than necessary to fix the other issues
if kscreen is running, so I'll leave it off.
So pending further posts to the thread otherwise, I'll declare this a
usable workaround here, and consider the problem now worked around.
Thanks again for the hint to go looking at that kscreen service. =:^)
