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
