PulseAudio
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. It serves as a middleware in between applications and hardware and handles raw PCM audio streams.
PulseAudio is free and open-source software, and is licensed under the terms of the LGPL-2.1-or-later.
It was created in 2004 under the name Polypaudio but was renamed in 2006 to PulseAudio.
PulseAudio competes with newer PipeWire, which provides a compatible PulseAudio server (known as pipewire-pulse), and PipeWire is now used by default on many Linux distributions, including Fedora Linux, Ubuntu, and Debian.
On Microsoft Windows, PulseAudio runs in Windows Subsystem for Linux.
The NT kernel was previously supported via MinGW (an implementation of the GNU toolchain, which includes various tools such as GCC and binutils). The NT kernel port has not been updated since 2011, however.
In broad terms ALSA is a kernel subsystem that provides the sound hardware driver, and PulseAudio is the interface engine between applications and ALSA. However, its use is not mandatory and audio can still be played and mixed together without PulseAudio.
PulseAudio acts as a sound server, where a background process accepting sound input from one or more sources (processes, capture devices, etc.) is created. The background process then redirects these sound sources to one or more sinks (sound cards, remote network PulseAudio servers, or other processes).
