Mouse / keyboard multimedia keys Problem

[Fidelma]

On my keyboard I have a few multimedia keys volume + / volume - / mute. (gum right button on the keyboard more accessible than [ctrl ][+], [ctrl ][-], [M])
Act directly on the master volume.

Since version 9 VLC, these keys are not functional at all.
to adjust the volume, I (we) require VLC to move forward and plan to use the mouse wheel or a combination of keys.

I tried to reconfigure the keyboard shortcuts without success.

Normally the buttons can be customized in VLC in tools / preferences / interface / parameter

Thanks

The multimedia keys on my keyboard are not taken into account by VLC 9.0!

I do not think the problem comes from VLC because I have the same type of shortcuts and it's a problem with drivers of your keyboard.
