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 rightly so. There's a reason we're migrating away from pulse to pipewire.
For the longest time the solution to any audio issues was "just uninstall PulseAudio, and use plain ALSA", and that usually worked. I held out for years and ran an ALSA only setup because it just worked and PulseAudio was always giving me one issue or another (audio lag, crackling, unexplained muting), until some applications started to drop ALSA support.
Then Pipewire came along, and so far it has been rock solid for me.
Both were just a pain in their own right, IMHO. My previous Focusrite interface was quite fiddly to get working with ALSA and just worked OOTB with Pulseaudio. I also don’t miss messing with ALSA/JACK at all.
Pipewire has pretty much been a drop-in replacement for me, with how it can act as a Pulseaudio backend.
Possibly hardware dependent?
I always had audio hardware that was well supported by ALSA, I never had any ALSA issues until applications stopped supporting it.
Does pipewire interface directly to drivers or is it user-space magic on top of alsa like pulseaudio?
It runs on top of ALSA, as far as I know.
I believe it is U-space on top, but I could be wrong.
