This adds a set of home shepherd services which will start the required
services for a functional pipewire setup.
* gnu/home/services/sound.scm (home-pipewire-shepherd-service),
(home-pipewire-pulse-shepherd-service), (home-wireplumber-shepherd-service),
(home-pipewire-shepherd-services), (generate-doc): new procedures.
(home-pipewire-service-type): new service type.
(home-pipewire-configuration): new struct.
* doc/guix.texi (Sound Home Services): document it.

+@cindex PipeWire, home service
+
+@uref{https://pipewire.org, PipeWire} provides a low-latency,
+graph-based audio and video processing service. In addition to its
+native protocol, it can also be used as a replacement for both JACK and
+PulseAudio.
+
+@defvar home-pipewire-service-type
+This provides the service definition for @command{pipewire}, which will
+run on login. Its value is a @code{home-pipewire-configuration} object.
+
+To start the service, add it to the @code{service} field of your
+@code{home-environment}, such as:
+
+@lisp
+(service home-pipewire-service-type)
+@end lisp
+
+@deftp {Data Type} home-pipewire-configuration
+Available @code{home-pipewire-configuration} fields are:
+
+@table @asis
+@item @code{pipewire} (default: @code{pipewire}) (type: file-like)
+The PipeWire package to use.
+
+@item @code{wireplumber} (default: @code{wireplumber}) (type: file-like)
+The WirePlumber package to use.
+
+@item @code{enable-pulseaudio?} (default: @code{#t}) (type: boolean)
+Enable PulseAudio replacement.
