Gamdias Hermes P2 keyboard multimedia keys are not working

Hi,

All functions of my Gamdias Hermes P2 keyboard are working on windows, even without the Hera software.
I'd like to use the volume control wheel and keys (Fn+F5..Fn+F8) on Linux, but no luck.
Tried to get scancodes with evtest, evemu-record, libinput debug-events, but nothing detected, when pressing e.g. Fn+F5, or rolling the volume wheel.
Picture of a similar keyboard

Is there any solution?

Thanks a lot in advance!
