You are right. I used the terminology because of the way I am ssh'ing from
and to.

"xprop -root | grep PULSE_COOKIE" does not turn up any results on the local
sound server or on the remote sound client side
"dpkg -L pulseaudio | grep start-pulseaudio-x11" does not turn up any
results on the local sound server side but
it does turn up results on the remote sound client side.

pacmd gives the error "No PulseAudio daemon running, or not running as
session daemon." on the local sound server side but
I managed to get around this by:
# stop pulseaudio
# pulseaudio --system --high-priority -C
and then at the pulseaudio command line: list-modules
Here is the module:
-------------------------------
index: 18
name: <module-native-protocol-tcp>
argument: <auth-anonymous=1>
used: -1
load once: no
properties:
module.author = "Lennart Poettering"
module.description = "Native protocol (TCP sockets)"
module.version = "0.9.15"
-------------------------------

No problems there.

"xprop -root | grep PULSE_COOKIE" does not give any results on the remote
machine.
