USE flags

  • abi_mips_n32 - 64-bit (32-bit pointer) libraries
  • abi_mips_n64 - 64-bit libraries
  • abi_mips_o32 - 32-bit libraries
  • abi_ppc_32 - 32-bit (ppc) libraries
  • abi_ppc_64 - 64-bit (ppc64) libraries
  • abi_riscv_lp64 - 64-bit (rv64) soft-float libraries
  • abi_riscv_lp64d - 64-bit (rv64) double hard-float libraries
  • abi_s390_32 - 32-bit (s390) libraries
  • abi_s390_64 - 64-bit (s390x) libraries
  • abi_x86_32 - 32-bit (x86) libraries
  • abi_x86_64 - 64-bit (amd64) libraries
  • abi_x86_x32 - x32 ABI libraries
  • alsa - Add support for media-libs/alsa-lib (Advanced Linux Sound Architecture)
  • alsa-plugin - Request installing media-plugins/alsa-plugins with PulseAudio plugin enabled. This ensures that clients supporting ALSA only will use PulseAudio.
  • asyncns - Use libasyncns for asynchronous name resolution.
  • avahi - Add avahi/Zeroconf support
  • bluetooth - Enable Bluetooth Support
  • caps - Use Linux capabilities library to control privilege
  • cpu_flags_arm_neon - Use the NEON (ASIMD) instruction set
  • daemon - Build the pulseaudio binary (not-needed for pipewire-pulse)
  • dbus - Enable dbus support for anything that needs it (gpsd, gnomemeeting, etc)
  • doc - Build the doxygen-described API documentation.
  • elogind - Use sys-auth/elogind for giving each session a PA client
  • equalizer - Enable the equalizer module (requires sci-libs/fftw).
  • gconf - Ensure gnome-base/gconf is present for pulseaudio GConf to GSettings module automatic migration (keeping the user configuration)
  • gdbm - Use sys-libs/gdbm to store PulseAudio databases. Recommended for desktop usage. This flag causes the whole package to be licensed under GPL-2 or later.
  • glib - Add support to dev-libs/glib-based mainloop for the libpulse client library, to allow using libpulse on glib-based programs. Build the GSettings PA module.
  • gstreamer - Add support for media-libs/gstreamer (Streaming media)
  • gtk - Add support for x11-libs/gtk+ (The GIMP Toolkit)
  • hal - Enable Hardware Abstraction Layer (HAL) support (WARNING: Try to avoid this. Deprecated method of accessing hardware.)
  • ipv6 - Add support for IP version 6
  • jack - Add support for the JACK Audio Connection Kit
  • kernel_linux - KERNEL setting for system using the Linux kernel
  • libressl - Use dev-libs/libressl instead of dev-libs/openssl when applicable (see also the ssl useflag)
  • libsamplerate - Build with support for converting sample rates using libsamplerate
  • lirc - Add support for lirc (Linux's Infra-Red Remote Control)
  • native-headset - Build with native HSP backend for bluez 5.
  • neon - Enable optimization support for ARM NEON processors
  • ofono-headset - Build with oFono HFP backend for bluez 5, requires net-misc/ofono.
  • orc - Use dev-lang/orc for just-in-time optimization of array operations
  • oss - Enable OSS sink/source (output/input). Deprecated, upstream does not support this on systems where other sink/source systems are available (i.e.: Linux). The padsp wrapper is now always build if the system supports OSS at all.
  • qt4 - Add support for the Qt GUI/Application Toolkit version 4.x
  • qt5 - Add support for the Qt 5 application and UI framework
  • realtime - Makes PulseAudio use RealtimeKit (sys-auth/rtkit) to get real-time priority while running.
  • selinux - !!internal use only!! Security Enhanced Linux support, this must be set by the selinux profile or breakage will occur
  • sox - Add support for Sound eXchange (SoX)
  • ssl - Use dev-libs/openssl to provide support for RAOP (AirPort) streaming.
  • system-wide - Allow preparation and installation of the system-wide init script for PulseAudio. Since this support is only supported for embedded situations, do not enable without reading the upstream instructions at https://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/WhatIsWrongWithSystemWide/ .
  • systemd - Build with sys-apps/systemd support to replace standalone ConsoleKit.
  • tcpd - Add support for TCP wrappers
  • test - Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)
  • udev - Enable virtual/udev integration (device discovery, power and storage device support, etc)
  • webrtc-aec - Uses the webrtc.org AudioProcessing library for enhancing VoIP calls greatly in applications that support it by performing acoustic echo cancellation, analog gain control, noise suppression and other processing.
  • X - Build the X11 publish module to export PulseAudio information through X11 protocol for clients to make use. Don't enable this flag if you want to use a system wide instance. If unsure, enable this flag.
  • zeroconf - Support for DNS Service Discovery (DNS-SD)
