A webcam's light has been intermittently coming on, and I'm trying to track down what program is accessing it (without just blindly killing programs until the light goes off).
I've gone through the standard steps: finding the "Physical Device Object" IDs in Device Manager, using Process Explorer to search open handles and which programs are accessing what, but this leads to "audiodg.exe" accessing the webcam handles, which is apparently the "Windows Audio Device Graph Isolation".
This is what's directly accessing the webcam, but I can't see what program called for its access in the first place, to see which program is pulling the puppet-strings, so to speak.
So is there a way to trace which program is accessing a webcam's microphone or video via "Windows Audio Device Graph Isolation", audiodg.exe?
