Q: 

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?

+1  A: 

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

This method returns that the thread execution state is already equal to ES_CONTINUOUS before and after the WaveInOpen call

Well, worth a try. You are looking at driver hacking next, no idea how to tackle that.
