Soundcard powerdown

[ipartola at clarku.edu (Igor Partola)]

Good time of day,

I found an interesting feature under the Windows installation on my 
laptop. It seems that when there is no sound playing the soundcard is 
shut off. I'm not sure how much power this would save but it is 
interesting that this is possible. Maybe this could appear on a distant 
wishlist.

Respect,
Igor
