PipeWire is a project that aims to greatly improve handling of audio and video under Linux. It provides a low-latency, graph based processing engine on top of audio and video devices that can be used to support the use cases currently handled by both PulseAudio and JACK.
PipeWire vs Advanced Linux Sound Architecture Comments
a small clarification, PipeWire is not a full replacement for ALSA because ALSA is a kernel-level sound framework. What PipeWire can be a drop-in replacement for is ALSA's userspace library: https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/FAQ#does-pipewire-replace-alsa


- PipeWire is Free and Open Source












PipeWire is a seamless drop-in replacement for ALSA that also handles JACK and PulseAudio applications at the same time.
