Speaker sleep mode

Like other people I purchased the dock so I can use my iPad or iPhone as an alarm as well as watch movies or listen to music.
Pointless when the speakers switch off but also override your devices sound too.
Note on your website none of your "commonly" asked FAQs mention this utterly ridiculous dilemma.
Please address, other than this the sound is so good it is such a shame.
