How to restore fn keys?

Hello, in General a situation such, stood manjaro, everything was fine, decided the second system to put windows 10.
After installing Windows and drivers in Linux (I tried different distributions) changed the action of fn buttons to adjust the brightness, now both buttons turn on/turn off the microphone (in Windows all is normal) there is a separate button on it, tried to reassign the settings, but all 3 buttons are now tied to the microphone. And if you put one, the others perform the same action. Were demolishing the Windows, updated the BIOS, nothing helps. In the BIOS keys are not configured separately, it can only be on/off.
Tell me how can I solve this problem. Thanks in advance.
The HP Probook 440 g6 (the laptop was without a system) first put manjaro, it worked fine, by the way immediately after installing Windows adjust the brightness fn keys were not working, earned only after installing the drivers.
