Davinci Resolve switches on webcam on launch

I don't know how this got switched on but Davinci Resolve 17.3.1 Build 5 is switching my webcam on when I launch it, before I even load a project. How do I turn this behaviour off? I don't recall setting this anywhere and it certainly wasn't doing it last week.

Strange.. check preferences video and audio I/O

I figured this out. For some reason my default microphone device in Windows 10 was my webcam. I switched that to my "big mic", restarted Resolve, and the issue has gone away.

Thanks for the update! I had a similar issue didn't realize Resolve was picking up my webcam mic by default. Switching to my main mic and restarting fixed it for me too. Appreciate the tip!
