- One step forward and one step back. Looks like there is a problem 
creating the tunnel with the version of pulse used in the ubuntu 9.04 
distribution. If I do the following on ubuntu 10.04 it works:

# Create a tunnel to the remote sound card
pactl load-module module-tunnel-sink "server= 
# Make it the default sink
pacmd set-default-sink sink-DGTM

- Unfortunately this does not work on ubuntu 9.04. The syslog shows:

Nov 13 14:45:33 ubuntu-JMRT pulseaudio[3473]: module-tunnel.c: Stream died.

- In case someone is interested in seeing what happened when I tried 
this in 9.04, I have attached the complete terminal session as a text file.

- So I am going to assume that there is a bug in this version. 
Although it does work with padevchooser, I can not get it to work 
from the command line. I also tried adding the following 
to  /etc/pulse/default.pa and got the same results:

### Make some devices default
#set-default-sink output
load-module module-tunnel-sink server= 
sink=alsa_output.pci_8086_293e_sound_card_0_alsa_playback_0 sink_name=sink-DGTM
set-default-sink sink-DGTM
#set-default-source input

- syslog:
Nov 13 14:45:33 ubuntu-JMRT pulseaudio[3473]: module-tunnel.c: Stream died.

- So, unless someone has a better suggestion, I am back to trying to 
figure out where to export PULSE_SERVER so that apps launched from 
gnome see it when I reboot. Any pulse/ubuntu guru's out there? :)
