I want to use the network to play a mp3 file in the server, and have it playing in all clients headphones (it's a classroom with several PCs).

So I'm trying at home first. I have a Debian Jessie server (with PulseAudio 5.0 installed by default), and an Ubuntu 16.04 as the client (with PulseAudio 8.0 installed by default). Following the instructions here, I have:

On the server:

sudo apt-get install pulseaudio-module-zeroconf

that was the only missing part, as attested by apt-cache policy. There is no /etc/default/pulseaudio on my system, it seems it already starts up automatically. Still added the following lines to /etc/pulse/system.pa:

load-module module-native-protocol-tcp auth-ip-acl=127.0.0.1;192.168.0.0/24
load-module module-zeroconf-publish

Then restarted the daemon:

pulseaudio -k

On the client:

Edited /etc/pulse/default.pa to add the line:

load-module module-tunnel-sink-new server=192.168.0.13 sink_name=Remote channels=2 rate=44100

where 192.168.0.13 is the IP of the server in the local network. Just like in the server:

pulseaudio -k

I see in the System Monitor that pulseaudio have correctly restarted in both server and client. But when I play an audio file in the server (for instance, with Audacity), I still couldn't hear anything in the client speakers.

So I installed paprefs on Debian (seems not available in Ubuntu Software Center anymore, I only found pavucontrol there), and checked both options in Network Server|Enable network access to local sound devices, Multicast/RTP|Enable Multicast/RTP receiver and sender|Send audio from local speakers. Still nothing. Wonder if these paprefs options somehow conflict with the first editions in /etc/pulse/system.pa?

Of course I'm missing something, but what? I've seen many similar questions over here, but most are years old (here, here, here and here), and even the newest one suggests the installation of new software. I'd really like to use the existing software (i.e. pulseaudio), if possible.

    Looks like after a reboot in both machines, and installing paprefs in Ubuntu it worked. Strange that paprefs don't show in the Software Center app, but is there if you type sudo apt-get install.... Isn't it strange? – Rodrigo Mar 23 '17 at 16:42
  • that's and answer, could you please copy it from comment to an answer and set as accepted. It will be easier to point out. – user.dz May 28 '21 at 10:21
