Macbook Pro late 2013 speaker problem
The internal speaker becomes buzzy and squeaky. Could it be some software problem? Or likely hardware thing that I need to bring it to Apple Store for repair? Thank you.

Safe Mode may help.
How to use safe mode on your Mac - Apple Support
Note: Safe mode prevents your Mac from loading certain software as it starts up, including login items, system extensions not required by macOS, and fonts not installed by macOS. It also does a basic check of your startup disk, similar to using First Aid in Disk Utility. And it deletes some system caches, including font caches and the kernel cache, which are automatically created again as needed.
