Thanks in advance for any help.

in Sound Mixer applet
lower MasterMono volume to zero for muting
raise Master volume for headphone volume controls

Isn't that a function of the laptop hardware? ie the physical insertion
of the headphone jack pushes on a switch inside the port to
tell the laptop to mute the speakers. I don't see how alsa could
diagnose that a headphone was plugged in without a switch in
the port or some kind of continuity detection in the hardware
(without the headphones the resistance is ~ infinite but with
the headphones it's 50ohms or whatever so that's another
way the laptop could tell but it's still a physical thing in the
