2017 Macbook Pro volume is too low

Question

My cat walked on my keyboard/mouse/touchbar and now my volume is too low. It happens with both headphones and using the internal speakers. I've looked at Audio/Midi settings and everything seems okay there, but testing still plays the audio too quiet.

What kind of secret "low volume" setting did my cat engage and how do I reverse it?

Answer 1

I just solved my own problem with an NVRAM/SMC/PRAM reset. The world may never come to understand what secret Mac fu cats possess.
