PC Won't sleep / hibernate. Audio driver issues?

[Ergo_Whatnot]

Hi,

Thanks in advance for the help.

My PC won't sleep / hibernate unless manually told to do so. I've tried messing with power options and network adapter power management settings to no avail. In my ramblings I came across the "powercfg -energy" tool. Great report. Hopefully found my problem, that being my audio driver making a request preventing the system going to sleep.

Is there a fix for this? I've tried downloading the "original driver" from HP with no luck. Perhaps I am looking in the wrong places.

The most recent report is included below. Complete with 9 errors and 5 warnings.

I'm running Win7 64 bit.

Thanks again.

Platform Power Management Capabilitiesupported Sleep States

Sleep states allow the computer to enter low-power modes after a period of inactivity. The S3 sleep state is the default sleep state for Windows platforms. The S3 sleep state consumes only enough power to preserve memory contents and allow the computer to resume working quickly. Very few platforms support the S1 or S2 Sleep states.

 S1 Sleep Supported true

 S2 Sleep Supported false

 S3 Sleep Supported true

I would recommend you to try the steps of uninstalling the audio driver from device manager, restart the computer and then try to install the same from this website
