Windows 7: Configure device to allow automatic standby

When I direct my computer to go into standby mode, it does so properly every time. However, it often will not enter standby mode on its own. I poked around a bit and think that I found the culprit - I have a jukebox-like program and I think that this indirectly causes the problem. When I ran powercfg -energy, this appeared in the report:



System Availability Requests:System Required Request
The device or driver has made a request to prevent the system from automatically entering sleep.

Requesting Driver Device Realtek High Definition Audio

My question is this: Is there some way to 'configure' the device such that it will not prevent the computer from entering standby mode?

Thank you.
