-Ubuntu Sound Menu
-=================
-
-The `Ubuntu Sound Menu <https://wiki.ubuntu.com/Sound#menu>`_ is the default
-sound menu in Ubuntu since 10.10 or 11.04. By default, it only includes the
-Rhytmbox music player, but many other players can integrate with the sound
-menu, including the official Spotify player and Mopidy.

-If you install Mopidy from apt.mopidy.com, the sound menu should work out of
-the box. If you install Mopidy in any other way, you need to make sure that the
-file located at ``extra/desktop/mopidy.desktop`` in the Mopidy git repo is
-installed as ``/usr/share/applications/mopidy.desktop``, and that the
-properties ``TryExec`` and ``Exec`` in the file points to an existing
-executable file, preferably your Mopidy executable. If this isn't in place, the
-sound menu will not detect that Mopidy is running.
-
-Next, Mopidy's MPRIS frontend must be running for the sound menu to be able to
-control Mopidy. The frontend is enabled by default, so as long as you have all
-its dependencies available, you should be good to go. Keep an eye out for
-warnings or errors from the MPRIS frontend when you start Mopidy, since it may
-fail because of missing dependencies or because Mopidy is started outside of X;
-the frontend won't work if ``$DISPLAY`` isn't set when Mopidy is started.
-
-Under normal use, if Mopidy isn't running and you open the menu and click on
-"Mopidy Music Server", a terminal window will open and automatically start
-Mopidy. If Mopidy is already running, you'll see that Mopidy is marked with an
-arrow to the left of its name, like in the screen shot above, and the player
-controls will be visible. Mopidy doesn't support the MPRIS spec's optional
-tracklist interface yet, so you'll not be able to select what track to play
-from the sound menu. You can use the sound menu to check what you're currently
-playing, pause, resume, and skip to the next and previous track.
-
-In summary, Mopidy's sound menu integration is currently not a full featured
-client, but it's a convenient addition to an MPD client since it's always
-easily available on Unity's menu bar.

-Rygel
-=====
-
-Rygel is an application that will translate between Mopidy's MPRIS interface
-and UPnP, and thus make Mopidy controllable from devices compatible with UPnP
-and/or DLNA. To read more about this, see :ref:`upnp-clients`.
