Thanks for your help, but I figured out what was going on.
As penance for wasting your time on this, I’ll tell you the stupid thing I did:
My headphones weren’t working for some reason and I was trying to listen to the headphone-made recordings before disconnecting from the headphones. Therefore all the headphone recordings didn’t make a noise.
For some reason, my headphones outputted some feedback but no audio, this gave me the impression that the problem was the input not the output.
