The control is named "Master Front".

Ah thanks. Didn't know about this switch. This presents the same mixer 
controls as without PA running.

None of the controls in alsamixer move when I move the slider in 
pavucontrol, and none of the pavucontrol sliders move when I change the 
"Master Front" volume in alsamixer.
