The functionality is enabled, but the default timeout is 0 seconds (never power down). You may have to specify a timeout. 10 seconds works well for me, but you can try something more aggressive like 3 seconds if you want to see quick response on your measurements. Generally you can hear the power up as an audible pop as you start playback. Regards, Tony V.
