thanks for reply. I had used "volume" as following code to achieve it.

  self.player = gst.element_factory_make("playbin2", "player")
  fakesink = gst.element_factory_make("fakesink", "fakesink")
  self.player.set_property("video-sink", fakesink)
  # output volume from 0.0 to 10.0
  self.player.set_property("volume", 1.0)
