Original commit message from CVS:
Patch by: Brian Cameron <brian dot cameron at sun dot com>
* sys/sunaudio/gstsunaudiomixerctrl.c:
(gst_sunaudiomixer_ctrl_open), (gst_sunaudiomixer_ctrl_build_list),
(gst_sunaudiomixer_ctrl_new), (gst_sunaudiomixer_ctrl_set_volume),
(gst_sunaudiomixer_ctrl_set_mute):
* sys/sunaudio/gstsunaudiosink.c: (gst_sunaudiosink_class_init),
(gst_sunaudiosink_init), (gst_sunaudiosink_prepare),
(gst_sunaudiosink_write):
Attached find a patch that fixes a number of bugs with the SunAudio mixer
plugin and fixes #344101:
1. The gst_sunaudiomixer_ctrl_build_list kept appending the same 3 tracks onto
the tracklist causing gnome-volume-control's preferences dialog to be messed
up and would core dump if you checked/unchecked any item.
2. We weren't previously setting the MUTE flag properly.  Fixing this makes
gnome-volume-control work better.
3. Now we properly define the input track to be GST_MIXER_TRACK_INPUT and
the monitor to be GST_MIXER_TRACK_OUTPUT, so that makes gnome-volume-control
look better.
Also some minor cleanup in gstsunaudiosink.c.
