Xbox one media remote can't adjust sound volume [Vero 4K]

The device is Vero 4K, and I use Xbox one media remote find that sound volume key isn’t work.

So can I fix it? How to do it? Thank you

Did you configure an LIRC keymap via My OSMC -> Remotes?
I don’t know a lot about this remote, but you may need to stop Kodi and use irrecord to create your own key mapping.

I find key editor addon maybe it can solve it.

Thanks Sam~ I will be check again
