Keyboard Volume Keys not working while in-game

I happen to have used the Tt Challenger Pro keyboard in the past, and the volume keys worked flawlessly in every game, so it's indeed a weird problem. I would suggest the same thing sneekypeet suggested, using the keyboard software and assign this function to a hotkey, but you said that didn't work either, so yeah...

 

Changing brightness is no longer smooth with function keys on 1903

Hi, There's a the slider for brightness at the bottom of the Action Centre (build 1903).

If you'd be prepared to consider an alternative... how about smooth control of brightness using your scroll wheel?
Press a key, plus scroll, and adjust your brightness.

The key and the steps are your choice.

Oh, and it can adjust volume similarly.

Works nicely on my Lenovo Thinkpad, where the Fn key steps for brightness are a bit harsh.
