Yes, it does print, PULSE_SERVER(STRING) = "zombie".

 If yes,

Fails completely.

 Does it print error messages?

paplay /usr/share/tuxtype/sounds/splat.wav
Connection failure: Access denied

xine, configured to use PA though, fails back to local sound.

The fix, of course, is to tell PA where to get the cookie to use that server:

pax11publish -e -c /etc/pulse/.pulse-cookie-zombie -S zombie

Thanks for the help, Tanu.

FWIW, here are the commands I plan to use to attach to a (panel)
launcher to make it easier to toggle between sound servers:

REMOTE:
ssh zombie 'cat /var/run/pulse/.pulse-cookie' | sudo sh -c 'cat >
/etc/pulse/.pulse-cookie-zombie' && sudo chown pulse:pulse-access
/etc/pulse/.pulse-cookie-zombie && sudo chmod 640
/etc/pulse/.pulse-cookie-zombie && pax11publish -e -c
/etc/pulse/.pulse-cookie-zombie -S zombie

and

LOCAL:
pax11publish -r
