Update:

The sound control (pavucontrol) is still accessible from the
Multimedia menu, but it doesn't respond to the keyboard as it used to
- I have a Dell keyboard with multimedia controls, and they're all
dead.

I suppose I took it for granted they'd continue to work, and nothing.

Disappointing....
