MacBook Pro 14" built-in speaker audio unreasonably low
I have this issue for almost 2 months now and I can't figure out why is my output audio is low. It's not loud as it used to be it's like it decreased by 2 bars or something. And the type of MacBook I got it is a 2021 M1 Pro 14 inch. I tried different methods that the internet told me which are force quitting my core audio, resetting my laptop, disconnecting the bluetooth, cleaned the grills, and so much more, but that doesn't work. I also updated the new software recently as well, but that doesn't work either. This laptop is unable to reset NVRAM because it's a Apple Silicon. I want to know if anyone experience this problem before or currently, and is it the laptop that is acting strange or something?
