+
+The new sound-server USE flag for PipeWire allows easily controlling
+this behavior.
+
+There are several options available:
+
+1. To use PipeWire for sound, users should enable USE=sound-server for PipeWire:
+
+ Place the following entries in /etc/portage/package.use:
+ ```
+ media-video/pipewire sound-server
+ media-sound/pulseaudio -daemon
+ ```
+
+ First, sync:
+ $ emerge --sync
+
+ Deselect media-sound/pulseaudio-daemon:
+ $ emerge --deselect media-sound/pulseaudio-daemon
+
+ Then perform a world upgrade:
+ $ emerge --ask --update --changed-use --deep @world
+
+ Then depclean:
+ $ emerge --ask --depclean
+
+ OpenRC users on an XDG-compliant desktop which respects autostart files
+ will not need to take any further action.
+
+ OpenRC users using a minimal desktop which does not respect autostart
+ files will need to run `gentoo-pipewire-launcher &` in e.g.
+ `~/.xprofile`.
+
+ systemd users will also need to run the following commands:
+ $ systemctl --user --now disable pulseaudio.service pulseaudio.socket
+ $ systemctl --user --now enable pipewire.socket pipewire-pulse.socket
+ $ systemctl --user --now disable pipewire-media-session.service
+ $ systemctl --user --force enable wireplumber.service
+
+2. To use PulseAudio's daemon for sound, users should disable USE=sound-server for PipeWire,
+ enable USE=daemon on media-sound/pulseaudio, and add media-sound/pulseaudio-daemon to
+ their world file:
+
+ Place the following entries in /etc/portage/package.use:
+ ```
+ media-video/pipewire -sound-server
+ media-sound/pulseaudio daemon
+ ```
+
+ Add media-sound/pulseaudio-daemon to @world:
+ $ emerge --noreplace media-sound/pulseaudio-daemon
+
+ Then perform a world upgrade:
+ $ emerge --ask --update --changed-use --deep @world
+
+ Then depclean:
+ $ emerge --ask --depclean
+
+ OpenRC users on an XDG-compliant desktop which respects autostart files
+ will not need to take any further action.
+
+ OpenRC users using a minimal desktop which does not respect autostart
+ files should consider adding `gentoo-pipewire-launcher &` in e.g.
+ `~/.xprofile` but it's not strictly required in terms of audio
+ handling. It may be required in future for the non-audio usecases
+ described above.
+
+ systemd users will also need to run the following commands:
+ $ systemctl --user --now enable pulseaudio.service pulseaudio.socket
+ $ systemctl --user --now disable pipewire.socket pipewire-pulse.socket
+
+3. For users without sound on their system, those using JACK without
+ PipeWire, or those using pure ALSA without PipeWire, the following steps >+ are recommended:
+
+ Place the following entries in /etc/portage/package.use:
+ ```
+ media-video/pipewire -sound-server
+ media-sound/pulseaudio -daemon

This is unecessarily restrictive to force the user to choose between
pipewire and pulseaudio for the sound server. It is possible (I am
running it now), and should be possible for gentoo to have both
installed simultaneously and run one or the other at any given time,
through configuration files.
[I think the only patch that is required is for alsa-plugins/pulse/conf_pulse.c: (conf_pulse_hook_load_if_running)
which can be taught to check if the pipewire daemon is running and
quit that particular module. but it is not pipewire aware yet]
