[$] PipeWire: The Linux audio/video bus

For more than a decade, PulseAudiohas been serving the Linux desktop as its predominant audiomixing and routing daemon - and its audio API. Unfortunately,PulseAudio's internal architecture does not fit the growingsandboxed-applications use case, even though there have been attempts to amend that. PipeWire, a new daemon created (in part)out of these attempts, will replacePulseAudio in the upcoming Fedora 34 release. It is a comingtransition that deserves a look.
