Here is a explaination of how ive been about things and what my issues
are:
Computers:
laptop - Lucid Ubuntu 10.4 - PulseAudio 0.9.21-32-g8478 Compiled with libary
version: 0.9.14
desktop- Karmic Ubuntu 9.10 - PulseAudio 0.9.19 Compiled with Libary Version:
0.9.14
Desired setup:
laptop = slave
desktop= master
I'm trying to get my Desktop to broadcast the music on BOTH laptop and
desktop's speakers
Software/Gui's:
pavucontrol
pavdevchooser
paprefs
The only way i could obtain any kind of results was by using pavdevchooser,
with the following settings:
In the paprefs of BOTH the desktop & laptop, gui i have the following:
Network Access
Make discoverable PulseAudio network sound devices available locally
Network Server
Enable network access to local sound devices
Allow other machines on the LAN to discover local sound devices
Don't Require authentication
Everything else is unticked, including the multicast/RTP tab and Simultaneous
Output
At this stage, pavdevchooser can see both machine's server on each computer.
how ever the only way i can get audio played on an oposite computer, is it set,
lets say in this case the hyperstream-desktop to have a default server of the
hyperstream-laptop, then if i open a rhythmbox player and play, it will play
ONLY on the hyperstream-laptop, but not on its OWN speakers.
And vice versa if i do it around the otherway.
How ever someone in the #pulseaudio channel, told me pavdevchooser is outdated,
and to use pavucontrol.
also that on the laptop i should only enable the Network server and the two sub
options, and on the master to enable the network access sub option.
The only other horrible way i have manage to stream music is to setup the
laptop as a multicast/RTP receiver, and the desktop as a multicast/RTP sender,
but as im sure you are aware it goes out of tune, out of sync, and isnt very
nice at all.
I had a friendly user in #pulseaudio attempt to show me how to use the pacmd to
do it 'manually', but i have failed lol, i will demostrate how to reproduce the
error:
(THIS IS DONE ON THE MASTER (desktop - the desktop machine has itself set as
server at this stage and is playing sound through its own speakers))
run pacmd in a terminal:
>>>load-module module-tunnel-sink server=hyperstream-laptop
>>>list-sinks
(THIS IS WHERE I GET LOST, i was asked to take note of the 'name of tunnel
sink' and the 'local sink')
2 sink(s) available.

As you can see, i cannot find a name for the local sink tunnel, so im using the
name of the index 0 sink.
PLEASE NOTE: on the after the last steps, the desktop is sending 180KB's
outgoing. the laptop is not receiving anything.
Any help would be great, thanks in advance
