gnome-media-2.8.0-gst-mixer-nomodem.patch in gnome-media 2.8.0-3 is
broken. It doesn't reset the element state if it found no tracks, and
thus therefore the next device in the list will not actually open
(since open is done between NULL and READY) and thus the next device
will not show up in the list.

+      if (!page)
+       continue;

Should change to:

+      if (!page) {
+        gst_element_set_state (element, GST_STATE_NULL);
+        continue;
+      }
