Volume issue with ARC HDMI

[peepshow-21]

Hi,

When I connect my kodi box (Rpi) to my TV, it connects via the HDMI ARC. If I press the volume up/down command on the keyboard that would normally change the GUI volume circle on Kodi, it goes via ARC to the TV volume instead, this work perfectly.

However, if I send the volume up/down to Kodi via the MQTT, is changed the volume within Kodi only, it does not behave as the keys do.

Can this be changed to work as per the keys? This would be very useful..
