It also provides an audio server which can replace PulseAudio. It will likely also require re-configuration of JACK clients, because they will attempt to use their old configuration files, if such exist.Īlternatively it should be possible to have PipeWire connect to a real jackd and act as a gateway for non-JACK applications but, unless there already is a working JACK setup, this is not recommended for the overall worse user experience with JACK.PipeWire is a multimedia server, best known for it’s video support in Wayland. Some may even ungracefully exit due to missing symbols. It should be noted that either due to PipeWire incompleteness or Gentoo configuration shortcomings, not every client will work. Failure to do this will likely cause at least occasional buffer underuns (xruns) as a single page fault is likely to spend half to the entire length of a buffer just in kernel time to resolve.
#GENTOO PULSEAUDIO HOW TO#
For instructions on how to achieve that please see the subsection on that below (also listed in the table of contents for this page). The only tricky part is that there is no truly standardized way (outside of systemd, of course) to actually do this and users need to choose the correct approach based on how their graphical shell is started, which has been summarized in the following table:Įxisting JACK users are likely to have realtime capability set up but new users are advised to raise the RLIMIT_MEMLOCK value from Gentoo's default of 64 kilobytes to 256 kilobytes on all PipeWire users that want to use its JACK emulation. On such systems starting PipeWire is as simple as starting the pipewire binary. Both requirements should be automatically met when any one of the desktop profiles is being used thanks to their elogind integration. PipeWire relies on a working D-Bus user daemon as well as XDG compliant environment. OpenRC with elogind (any of Gentoo's desktop profiles) To also replace PulseAudio and/or JACK, one must additionally follow the appropriate instructions elsewhere in this page. non-PipeWire clients continue using the same libraries and services they were using previously. In these cases, the -now flag is optional but probably safe to use as starting PipeWire with default configuration merely allows using new interfaces but does not change the existing ones i.e. The following systemctl command enables systemd's socket activation of PipeWire for the current user: PipeWire provides socket and service files when built with the systemd USE flag. Starting PipeWire with user session systemd In principle, existing PulseAudio or JACK tools can be used to interact with PipeWire when it is set up to behave as a JACK and/or PulseAudio server, but currently only parts of the respective APIs have been implemented. Additionally, PipeWire recognizes multiple environment variables that allow these settings to be changed, per-user, or for individual commands. Global PipeWire configuration can be changed by editing the /etc/pipewire/nf file, and ~/.config/pipewire/nf may be used for per-user configuration. Typically things work reasonably well out of the box, and PipeWire's global configuration is usually best left unmodified. PipeWire is still in heavy development - configuration paths, options and defaults can change from one minor release to another - if things on the system do not align with documentation, double check or at least make a backup before making changes.ĭetailed, non Gentoo-specific, configuration documentation can be found at the project's official wiki. PipeWire currently ships a PipeWire daemon, an example session manager, tools to introspect and use the PipeWire Daemon, a library to develop PipeWire applications and plugins, and the SPA (Simple Plugin API) used by both the PipeWire daemon and the PipeWire library. Applications sandboxing support with Flatpak, with a security model that facilitates interacting containerized applications.Seamless support for PulseAudio, JACK, ALSA, and GStreamer.Multi-process architecture allowing multimedia content sharing between applications.Minimal latency capture/playback of audio and video.It can be used to support use-cases currently handled by ALSA, PulseAudio, and/or JACK, and aims to improve handling of audio and video under Linux. PipeWire is a low-latency, graph-based, processing engine and server, for interfacing with audio and video devices.

While replacing existing audio solutions on Gentoo is possible, the experience is currently not guaranteed to be perfect or free of issues and bugs. As of early 2021 PipeWire is still in active development and not everything is fully integrated, tested, or implemented.
