Yeah, I know, its poor form to reply to ones own msgs.  But I found it, and I 
thought I'd share it for the lists archive, cuz I've a big dummy, and the 
answer was so darned obvious once I'd tripped over it.

If you right click on the speaker icon, a line has been added to it, "Select 
Master Channel...", which when clicked on, brings up a nice neat little gui I 
never saw before, and which lets you assign this mouse wheel volume control 
to any channel of either card.

I tell you, they'll actually re-invent the amiga's "Intuition" interface yet, 
I mean who woulda thunk it might be in an intuitively obvious place like 
that?  Boggles the mind...

kde-3.5.7 just to nail that bit of jelly to the wall.
