Can't Record From Mic Input on Windows Laptop

Running Win 10, Audacity version 3.0.2. Using Win WASAPI. Mic input on laptop. Tried to record from reel to reel line out and headphone jack. Nothing. Tried to record from receiver headphone jack and monitor jack. Tried from receiver line out. Even using a mixer. Nothing. When I push record, I get this error message: error opening recording device. Error code -9996 invalid device. I attempted all of the things suggested to rectify the problem.
This also happens on my Win 10 desktop…same version of Audacity. I suspect the problem is operator error.

I found the answer to this. Go into privacy settings on your computer and make sure you microphone is enabled- if it is turned off, turn it on. That solved it for me. :slight_smile:
