i am attempting to forward audio (x11 video is already working) over my local lan from a source pc to a client pc. both machines are running ubuntu. i have followed these instructions but i'm getting some errors.
here is the result of the pax11publish command on each workstation:
[me@source ~] $ pax11publish
Server: {fb...05}unix:/home/me/.pulse/fb...05-runtime/native tcp:client-pc:4713 tcp6:client-pc:4713
Cookie: ac22 ... d0
[me@client ~] $ pax11publish
Server: {fb...05}unix:/home/me/.pulse/fb...05-runtime/native tcp:client-pc:4713 tcp6:client-pc:4713
Cookie: ac22...d0
to get these settings to work i configured paprefs the same on both the client and the source by ticking the following boxes:
network access tab > make discoverable pulseaudio network sound devices available locally
network server tab > enable network access to local sound devices
network server tab > allow other machines on the lan to discover local sound devices
simultaneous output tab > add virtual output device for simultaneous output on all local sound cards
i proceeded to ssh from the client pc to the source pc:
$ ssh -C -R 24713:localhost:4713 user@source_pc -X
and then on the source pc:
$ export PULSE_SERVER="tcp:localhost:24713"
note that i typed localhost literally here - didn't change it to the pc's name. should i have?
anyway... when i attempted to send audio from the remote server by starting up vlc, it gave the following errors:
$ vlc

help!
update
when i issue a beep at the source terminal:
echo -e "\a"
i do hear the beep, so maybe its just a problem with the vlc player config?
netstat -lnp | grep 4713ps ax | grep ....), take note of the pid, then run againnetstat -lnp | grep thepidyounoted). This will tell you the portpaprefssettings and now the port is showing up. i will update the question so you can see the output of this command. the same error is still coming up when i try and play across the network though.
