Bouzas: PipeWire, the media service transforming the Linux multimedia landscape

The mention to Flatpak is because PipeWire's security enforcement makes it possible to allow only limited audio access to Flatpak'ed applications. For example, you can allow an application to playback, but not to capture from a microphone, etc. While the PulseAudio model means that if you give access to an application, it has full access to the audio system.
