Sounds as if this might work then. But if hovering gives focus when you
go to say the input gain, won't you have the same complainant saying
that ALT+ SHIFT + Up won't then increase the Track Panel gain? I
suppose people can simply learn the shortcuts and do without clicking
in the first place, but that assumes sighted users are going to be
actively looking for shortcuts and I expect they aren't.

Reproduces straight away on my XP and Vista machines even on fresh boot.
Can you try scheduling something to happen that uses CPU then try using
the sliders? Here 15-20% CPU is enough to cause it, and momentary
instances of that are common. Does not affect dragging the slider, or
the toolbar display at all.
