Volume Control Device Mapping

[marcoxyz123]

The Volume Control in my activity is working with "Device Volume" and the Harmony Remote. What I need is a mapping of this "Device Volume" to another Zone.

Setup:

Roon -> rooUPNP -> FiiO M15 - ruark R5

AudioDevice: D1
Activity: Listen to Music

The FiiO M15 is using lineOut Fixed and roon and rooUPNP are using BitPerfect

Roon - rooUPNP - ruark R5

AudioDevice: D2

per rooUPNP i am able to change the volume of the ruark R5 because the ruark R5 is not Harmony compatible.

It would be perfect with an option: Use The Volume of D2 with the Activity from D1

Best regards
Marco
