Hi, Here are my results.... <div class="gmail_quote">On Sat, May 21, 2011 at 7:58 PM, Colin Guthrie <<a href="mailto:gmane@colin.guthr.ie">gmane@colin.guthr.ie</a>> wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> Hi, I think you're maybe getting a little confused by client and server in terms of how things work here (perhaps not, as I've not thoroughly read all the many posts in this thread). </blockquote><div> You are right. I used the terminology because of the way I am ssh'ing from and to. </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> 2. Open a terminal and type: "xprop -root | grep PULSE_COOKIE" Ensure this has some output. If it does not then chances are the "start-pulseaudio-x11" script was not run at login (or you have restarted your PA server after logging in). Try just running "start-pulseaudio-x11" and see if that fixes it. </blockquote><div> "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. </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> 3. Ensure that the tcp native protocol module is loaded. "pacmd list-modules | grep module-native-protocol-tcp" If it is not loaded, then simply type: "pactl load-module module-native-protocol-tcp" </blockquote><div> 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" ------------------------------- </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> 4. SSH to your other machine: ssh -X -R4713:localhost:4713 OTHERMACHINE If you get a warning: Warning: remote port forwarding failed for listen port 4713 then chances are there is a PA daemon running there already, or you've SSH'ed twice. If the former, just change the *first* instance of 4713 to a random number of your choice (>1024). </blockquote><div> No problems there. </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> 5. On this remote machine, check your cookie is available via the xprop command show in step 2. If X11 forwarding is working properly, it should show up fine. </blockquote><div> "xprop -root | grep PULSE_COOKIE" does not give any results on the remote machine. </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> 6. Set the PULSE_SERVER variable to the forwarded tunnel port. <div class="im"> export PULSE_SERVER=localhost:4713 </div>(or the port number you picked in step 4 if different) 7. Confirm it's all working: PULSE_LOG=99 pactl stat </blockquote><div>Results of "PULSE_LOG=99 pactl stat" on the remote sound client side: ----------------------------------------- Using shared memory pool with 1024 slots of size 64.0 KiB each, total size is 64.0 MiB, maximum usable slot size is 65472 Trying to connect to localhost:4713...

So in this setup, the cookie used for authentication is forwarded automatically via piggy backing on to X11 connections but as you cannot connect directly to the machine we've had to override the PULSE_SERVER variable to go over the SSH tunnel. Below is the output from my session where I run these exact commands (note the host name in the pactl stat at the end).
