PC unexpectedly wakes from sleep
Every once in a while my PC wakes up a few seconds after I put it to sleep.
"Powercfg -lastwake" shows
I have two audio adapters but neither of their instance paths match that:Code:Wake History Count - 1 Wake History [0] Wake Source Count - 1 Wake Source [0] Type: Device Instance Path: PCI\VEN_8086&DEV_A348&SUBSYS_86D41043&REV_10\3&11583659&0&FB Friendly Name: Description: High Definition Audio Controller Manufacturer: Microsoft
HDAUDIO\FUNC_01&VEN_8086&DEV_280B&SUBSYS_80860101&REV_1000\4&2B5000E5&0&0201
and
HDAUDIO\FUNC_01&VEN_10EC&DEV_0887&SUBSYS_104386D4&REV_1003\4&2B5000E5&0&0001
Also, neither of them has a setting for waking the PC.
My Ethernet adapter does have that option set (when a "magic packet" is received) but its instance path is another non-match:
PCI\VEN_10EC&DEV_8168&SUBSYS_86771043&REV_15\4&AC99AD7&0&00EB.
Is there any way to find the device that matches the instance path in question without going through every device? I suspect I'm not going to find a match but I don't trust my eyes to find the (probably missing) match.
Is there a way that Windows would mislabel a device as an audio controller when it is something else?
In general, how do I debug this?
