volume controls on analog headphones are purely analog, the computer 
doesn't even know its there, its just an attenuator on the analog signal.

Hi all,

Thanks for your help...

On Centos-7, some apps use PulseAudioVolumeControl (pavucontrol)
instead of the one that defaults to the top panel. (I am running
Mate, not Gnome--yuck--so YMMV).

I wish there was a way to control all from a single place, but AFAICF
there isn't. for some things I use the one on the top panel (which is
Mate Volume Control) and for others I gotta start up pavucontrol.
it's a nuisance.

My USB phones seem to be controlled by the pavu control, while the
speakers tend to be controlled by the mate volume control. and I can't
get my old analog (1/8 inch plug) headphones to work at all anymore,
no matter what control I use or how I poke at it, all the sound comes
from the speakers (which are plugged into the line out [green} jack
on the rear of the computer, while the headphones are plugged into the
green jack on the front.)

digressing a little... A few years ago my systems all supported
auto-switching between speakers and headphones when the phone plug
was inserted, but the only one I have now that does that is my netbook.
the current desk-side system and its last couple of predecessors now
do not do that. Go figure.

Not sure, volume control on my USB headphones work just fine on CentOS 
7. Both on the headphones itself and from the desktop.


On both my home built PC and on my Thinkpad T410 (where it also works 
from volume buttons on keyboard)


I use MATE though, but I don't know if that is why.
