+@deffn {Scheme Variable} pulseaudio-service-type
+This is the type for the  @uref{http://www.pulseaudio.org/, PulseAudio}
+sound server.  It exists to allow system overrides of the default settings
+via @code{pulseaudio-configuration}, see below.
+
+@quotation Warning
+This service on its own does not ensure, that the @code{pulseaudio} package
+exists on your machine.  It merely adds configuration files for it, as
+detailed below.  In the (admittedly unlikely) case, that you find yourself
+without a @code{pulseaudio} package, consider enabling it through the
+@code{alsa-service-type} above.
+@end quotation
+@end deffn
+
+@deftp {Data Type} pulseaudio-configuration
+Data type representing the configuration for @code{pulseaudio-service}.
+
+@table @asis
+@item @code{client-conf} (default: @var{()})
+List of settings to set in @file{client.conf}.
+Accepts a list of strings or a symbol-value pairs.  A string will be
+inserted as-is with a newline added.  A pair will be formatted as
+``key = value'', again with a newline added.
+
+@item @code{daemon-conf} (default: @var{((flat-volumes . no))})
+List of settings to set in @file{daemon.conf}, formatted just like
+@code{client-conf}.
+
+In addition to the above, @code{default-script-file} will be set to the
+value of @code{script-file}.  By default, @var{flat-volumes} is set to
+``no'', so as to avoid bugs related to this feature.
+
+@item @code{script-file}
+Script file to use as as @file{default.pa}.  Defaults to the one included by
+the @code{pulseaudio} package.
+
+@item @code{system-script-file}
+Script file to use as as @file{system.pa}.  Defaults to the one included by
+the @code{pulseaudio} package.

 @deffn {Scheme Variable} ladspa-service-type
 This service sets the @var{LADSPA_PATH} variable, so that programs, which
 respect it, e.g. PulseAudio, can load LADSPA plugins.
