From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

And the strangest thing about that is that neither PulseAudio nor Pipewire are replacing anything. ALSA and PulseAudio are still there while I handle my audio through Pipewire.
How is PulseAudio still there? I mean, sure the protocol is still there, but it’s handled by
pipewire-pulseon most systems nowadays ~~(KDE specifically requires PipeWire)~~.Also, PulseAudio was never designed to replace ALSA, it’s sitting on top of ALSA to abstract some complexity from the programs, that would arise if they were to use ALSA directly.
Pulse itself is not there but its functionality is (and they even preserved its interface and pactl). PipeWire is a superset of audio features from Pulse and Jack combined with video.
For anyone wondering: Alsa does sound card detection and basic IO at the kernel level, Pulse takes ALSA devices and does audio mixing at the user/system level. Pipe does what Pulse does but more and even includes video devices
