winapiwindows-7power-saving

Is it possible to an app that listens to the Windows audio input to let the system save power?

From the moment we call Win API's WaveInOpen method the system won't sleep nor hibernate until this stream is closed. Is there any workaround for this?

Solution

  • Wild guess: try calling SetThreadExecutionState(ES_CONTINUOUS) on the same thread that called WaveInOpen.
