This means on battery power if the audio device is not rendering audio for a continuous period of 30 seconds, it will actually switch the audio device to a D3 power state. By definition, this means the device is off and should not consume any energy at all. Whilst Microsoft doesn¡¯t give any indication of potential power savings, I presume this will have more of an effect than the VSync enhancement.
Before any of this matters, both of these changes also require some work on behalf of the hardware vendor. In the case of the graphics driver, it involves adding an additional flag in the source code and recompiling it with the new framework. In the case of the audio driver, it will have to direct the hardware to enter into a low-power state after a period of audio idle. Besides Microsoft¡¯s default drivers, I¡¯m not aware of any third-parties already supporting these enhancements but I hope they will soon.
If any laptop users with Vista SP1 have noticed a dramatic increase in battery life after SP1, please share your system specification and how much of an improvement you saw. If you don¡¯t have SP1 already, it only means you¡¯re not looking hard enough.
