My laptop stopped picking up sound from my microphone (USB) a few days ago for no apparent reason. I've tried two other headsets (not USB) and my laptop did not pick up sound from either. It's almost as if I muted it somehow, but I can't find anything that actually says it's muted. For the record, none of the 3 headsets have a mute button located on them.
My laptop recognizes that my headset is plugged in fine and I can hear sound through them fine. I have all my sound/recording options defaulted to my headset.

I have not done anything to my computer in the last few days. I have 4 USB ports and I've tried all 4, both with and without rebooting. I've tried reinstalling my sound drivers. Is there anything else I can look into or is something in my laptop borked?
