I don't have a Mackie, but had something similar happened with my
Soundcraft....  If you have inserts on your subgroups, try plugging
something in to it repeatedly to knock the tarnish off.

Apparently I had some crud in the normally-closed contacts in my subgroup
insert (that I hardly ever use) and working them a little with a cable
fixed it right up.  I suppose I should open it up and clean it properly,
but I have plenty of projects already :)

I don't know the signal path in the Mackie, but perhaps your "assign to
mix" is prefader?  If so, maybe the fader died... or a broken solder joint
at the fader?  

Otherwise, its probably time to run a test tone into the board and start
probing with your scope.  I bet you can find the schematics for that thing
online... or at least get them from Mackie.  

Good Luck!
