I have Logitech USB stereo headphones with boom mic plugged into USB. If I use its in-line control to change the volume, a volume indicator appears on-screen. The progress bar is blue when the volume is at the low setting, then gradually changes to white when the volume is increased.
Except, the volume coming out of the headphones, is not changing.
If I need to adjust the volume, I must launch the PulseAudio Volume Control and change it there.
Is what I'm describing above, the correct behavior? It would seem that when the volume is increased with the in-line control, the actual volume coming out of them /should/ increase?
If it were a normal pair of 3.5mm audio jack headphones, I would say "yes" immediately, but with something more complex, I'm always skeptical.
Have you tried plugging them into something else—phone, tablet, other computer, anything with a suitable jack—and seeing whether the volume control works as expected there? That's the first step: rule out the simple possibility of broken hardware.
(My next step would be to kill PulseAudio with fire regardless of whether there was a hardware problem or not, but I have no use for its extra features and it's possible that you do.)

My other desktop also has Debian 10/Trinity installed, so if I plugged these into that, I believe would have the same result. Only difference between the desktops, is the insides. Both systems are using plug-in audio cards (both Creative SoundBlasters, but different models).
