 If running headless, swap out pavucontrol for pulsemixer, and also install pulseaudio as well. Attempting to install pavucontrol in a headless environment may attempt to install a minimal desktop environment. Note: Default behavior of pulseaudio in a headless environment may be to be muted, so check by opening pulsemixer and unmuting and routing audio appropriately.
