I'm trying to list human-readable names for devices with pulsesink, just like I
do for alsasink where it works ok, using :
void
GST::AudioOutputManager::detect_pulsesink_devices ()
{
  GstElement* elt = NULL;

  elt = gst_element_factory_make ("pulsesink", "pulsesinkpresencetest");

  if (elt != NULL) {

    GstPropertyProbe* probe = NULL;
    const GParamSpec* pspec = NULL;
    GValueArray* array = NULL;

    gst_element_set_state (elt, GST_STATE_PAUSED);
    probe = GST_PROPERTY_PROBE (elt);
    pspec = gst_property_probe_get_property (probe, "device");

    array = gst_property_probe_probe_and_get_values (probe, pspec);

    if (array != NULL) {

      for (guint index = 0; index < array->n_values; index++) {

    GValue* device = NULL;
    gchar* name = NULL;
    gchar* descr = NULL;

    device = g_value_array_get_nth (array, index);
    g_object_set_property (G_OBJECT (elt), "device", device);
    g_object_get (G_OBJECT (elt), "device-name", &name, NULL);
    descr = g_strdup_printf ("volume name=ekiga_volume ! pulsesink device=%s",
                 g_value_get_string (device));

    if (name != 0) {

      devices_by_name[std::pair<std::string,std::string>("PULSEAUDIO", name)] =
descr;

      g_free (name);
    }

    g_free (descr);
      }
      g_value_array_free (array);
    }

    gst_element_set_state (elt, GST_STATE_NULL);
    gst_object_unref (GST_OBJECT (elt));
  }
}

Unfortunately, for pulsesink 'name' always ends up NULL...

The fact that the behaviour is different for alsasink and pulsesink makes me
think it's a bug.
