I'll explain briefly how it works and that may help you debug your env 
further.

I'll assume you're using a recent version of PA.

When pulse is started inside an X11 environment, an XDG autostart file 
should be run. /etc/xdg/autostart/pulseaudio.desktop

This runs the script start-pulseaudio-x11. This loads a module in the 
pulsedaemon (and starts it if it's not running yet) which allows the 
configuration to queried via x window properties.

If you do xprop -root | grep PULSE you'll see the values I'm referring 
to, but the important one is PULSE_SERVER.

When you ssh -X it will allow the remote machine to query the pulseaudio 
settings from the root window so doing xprop -root | grep PULSE after 
ssh'ing should give you the same result.

Using this variable it should be possible to connect back to your 
pulseaudio daemon, but it could be getting overridden somewhere else. 
e.g. you may have a client.conf (either in /etc/pulse or ~/.pulse) that 
overrides the server= argument for example.

If you can play about a bit, and set the standard environment variable 
PULSE_SERVER I'm sure you can trace where the problem lies.

Hope this helps.
