Q: Built-in sound input device "Line-in" dissapeared

Hello,

Somehow my sound input device "Line-in" dissapeared from my computer. When I go to System Preferences > Sounds > Input, the only input device listed there is "Internal Microphone". There used to be "Line-in" as well.

I think that happened when I installed a screen capture software "Movavi Screen Capture". That software installed it's own sound input device named "Movavi Sound Grabber" which replaced old one called "Line-In". After deleting the software, I have no line-in input device at all, I can't record any sounds from the computer.

Please help me to solve this problem.
