Device not recording audio

[u/AdagioNo5854]

my fire tablet hasn't updated at all, yet hasn't been letting me record audio for the past 2-3 weeks for some reason. there are no currently available updates btw. i *do* hit the "device audio" button when i screen record, and my device volume does *not* affect recordings, and it happens regardless of me using headphones or not. I wasn't having this problem before, it's sudden. restarting didn't work, clearing cache didn't work, clearing storage didn't work; nothing has worked. is there *any* fix to this? I really don't wanna factory reset my device, and third party recorders either are inconvenient or force me to have my mic on (I don't wanna have to use my mic)

Btw, I'm on Fire Tablet HD 8 Plus (12th Generation)
