+  <p>
+    PulseAudio is GNOME's low-level audio API.  It is what sits between
+    applications and the kernel's audio API.  PulseAudio lets you re-route
+    sound through the network, or to a Bluetooth headset.  It can mix several
+    sources of audio, or change the sample rate of an audio stream.
+  </p>
+
+  <p>
+    All the parts of Gnome that produce audio use PulseAudio in one way or
+    another, either directly, or indirectly through higher-level sound
+    manipulation APIs like <link xref="gstreamer">GStreamer</link>.
