How do I enable media keys on windows?

I have 4 media keys on my windows keyboard, [Play/Pause, Back, Forward, Mute] and a Volume knob. Whilst LibreOffice is focused, none of these buttons work. How would I go about enabling them (if it is possible at the moment)?

Hi, What behavior do you expect from the media keys when LO has focus? Would you like to use them to control media inside LO documents?

I want to support this question. Globally hooked multimedia keys must work unrelated on focused application or any other things and only when LO window focused they don’t.

I have the very same problem. LO captures globally hooked multimedia keys.

Bug 32664 - Keyboard volume keys don’t work when LibreOffice is in focus

OOo/AOO Bug 99520 - malfunction of multimedia keyboard

I am not sure this is a LO bug. On my machine HP-PC Win7 Home Prem 64-bit with hp-media keyboard everything works perfectly fine. Maybe a driver problem in Win.
