ALSA is part of the Linux kernel, while PulseAudio is middleware, a part of the lower levels of the desktop stack. So is SDL . Advanced Linux Sound Architecture ( ALSA ) is a software framework and part of the Linux kernel that provides an application programming interface (API) for sound card device drivers .
PipeWire is a server for handling audio, video streams, and hardware on Linux. [ 2 ] [ 3 ] [ 4 ] It was created by Wim Taymans at Red Hat . [ 5 ] [ 6 ] It handles multimedia routing and pipeline processing.

PulseAudio is a network-capable sound server program distributed via the freedesktop.org project. It runs mainly on Linux, including Windows Subsystem for Linux on Microsoft Windows and Termux on Android; various BSD distributions such as FreeBSD, OpenBSD, and macOS; as well as Illumos distributions and the Solaris operating system.
The application originally used the Pulseaudio sound server as it allowed effects to be added to audio streams with ease, [4] however, now runs exclusively on the PipeWire sound server after a port in 2021. [5] It is published under the GPL-3.0-or-later license. [2]
On a low-end machine, such as a 600 MHz C3, the pulseaudio server can use 30% of the CPU. This converts a silent media-server from one which can (just) play DVDs into one which can't. Most pulseaudio-compliant applications such as mplayer will happily fall back to using ALSA natively if p.a. is uninstalled.

OpenPorts.se, originally announced as ports.openbsd.nu in 2006, [9] was a custom-written web-site that does its own parsing of the ports tree structure and the updates, and has the functionality of tracking changes of a given port, having a shortcoming of not supporting some of the more complicated Makefile logic, and thus missing some 15% of ...
