Audio stream keeping system from sleeping

Recommended Posts

So my desktop won't ever go to sleep on its own (telling it to sleep works fine). I've ran powercfg -requests to see what is preventing it from going to sleep when I leave it idle and I come up with this:




Doing some looking around it says that somewhere there is an application or service running that has an audio stream open, but I don't know what that could be. I know I can do a command to have it ignore the request and sleep anyway, but I would prefer to find out what is doing it instead. Is there a way to track down what is using the audio stream?


My sound card is a Realtek ALC889; I have Realtek onboard audio on some other Windows 7 systems that don't exhibit this behavior though.


Here's a few system specs:


AMD Phenom II CPU, GeForce GTX 580 GPU

Windows 7 x64 & Internet Explorer 10


System tray programs running:





Logitech Gaming Software

Blizzard Battle.Net Launcher

Curse Client

Start by disabling your sound card in Device Manager.  

Then see if the system can properly sleep.


If your system does sleep, wake it and do a restart. If it still will not, try restarting anyway.

Then look for any Events or even software notifications identifying what is trying to access the sound card.


This could be as simple as a driver issue. (Grab the latest ones from Realtek) 

Or going to the other extreme could be spyware that is actively monitoring your microphone.
