It's not a property; it's an interface!

GstElement *sink = ..;
GstMixer *mixer = GST_MIXER (sink);
GList *channels = gst_mixer_get_channel_list (mixer), *item;

for (item = channels; item != NULL; item = item->next) {
  GstMixerChannel *c = item->data;

  //.. etc

There's some example code in the gst-sandbox, or look at
gnome-volume-control in gnome-media (gnome cvs).
