* configure.ac: Minor cosmetic change to convince the buildbot to
reautogen.
* sys/sunaudio/gstsunaudio.c: (gst_sunaudiosink_class_init),
(gst_sunaudiosink_init), (gst_sunaudiosink_getcaps),
(gst_sunaudiosink_pad_link), (gst_sunaudiosink_chain),
(gst_sunaudiosink_setparams), (gst_sunaudiosink_open),
(gst_sunaudiosink_close), (gst_sunaudiosink_change_state),
(gst_sunaudiosink_set_property), (gst_sunaudiosink_get_property):
More hacking.  Plays audio now.
