PipeWire

• PipeWire - a project that aims to greatly improve handling of audio and video under Linux. It aims to support the usecases currently handled by both PulseAudio and Jack and at the same time provide same level of powerful handling of Video input and output. It also introduces a security model that makes interacting with audio and video devices from containerized applications easy, with supporting Flatpak applications being the primary goal. Alongside Wayland and Flatpak we expect PipeWire to provide a core building block for the future of Linux application development. [1]

• https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/Config-PulseAudio#network-support - The PipeWire PulseAudio server has fairly complete network support, include RTP and ROC support.

• PipeWire: PipeWire Module: RAOP Discover - Automatically creates RAOP (Airplay) sink devices based on zeroconf information. This module will load module-raop-sink for each announced stream that matches the rule with the create-stream action. If no stream.rules are given, it will create a sink for all announced streams.

Simple Wireplumber GUI

• https://github.com/dyegoaurelio/simple-wireplumber-gui - With this tool you can easily rename and see the properties of your audio devices if you're running pipewire as your audio server and wireplumber as it's session and policy manager.

coppwr

• coppwr - a tool that provides low level control over the PipeWire multimedia server. It aims to expose and provide as many ways to inspect and control the many aspects of the PipeWire multimedia server as possible. It can be used as a diagnostic tool for PipeWire and to help develop software that interacts with it.
