At my home, I have a Raspberry Pi 3 connected to my amplifier. This Pi is running a PulseAudio Server. This way, I can send the audio output from any machines in my network. At least, machines that are running Linux (or other *NIX).

I have attached a HDMI monitor to my Pi. This monitor has also audio support. However, I want the output to go to the analogue output as that is where the amplifier is connected. Furthermore, my home network is both IPv4 and IPv6.

First, I disable the auto detect for audio hardware, and replace it with a manual specification, so it will output at the analogue output rather then the HDMI,

#### Automatically load driver modules depending on the hardware available
#load-module module-udev-detect
#### Use the static hardware detection module (for systems that lack udev support)
#load-module module-detect

# Force PulseAudio to use analogue audio
load-module module-alsa-card device_id=1

To enable the server, I load the module-native-protocol-tcp. With the auth-ip-acl I set the access control list to allow only connection from my network. auth-anonymous=1 allows anonymous authentication, which disabled the need for sharing cookies. Finally, I add list=, this makes sure it only listens on IPv4 addresses, as otherwise the raspberry pi server will show up twice in the network.
Publishing in the network is done with the module-zeroconf-publish module.

# Adding listen= to force it IPv4 only, otherwise it will use both IPv4 and IPv6 and it appears twice
load-module module-native-protocol-tcp auth-ip-acl=; auth-anonymous=1 listen=  
load-module module-zeroconf-publish
