You should be able to get that from the caps with something like:

  GstStructure *s;
  gint rate, channels;

  s = gst_caps_get_structure (caps, 0);
  if (gst_structure_get_int (s, "rate", &rate) &&
      gst_structure_get_int (s, "channels", &channels)) {
    g_print ("%d channels @ %d Hz\n", channels, rate);
  }
