Ideas , here is one.
If one logs on to the radio itself via SSH (enable remote acess in the
settings ) you can find this file Playback.lua .
/usr/share/jive/jive/audio/Playback.lua
This file contains volume maps , I'm not a programmer so I can't tell
which one of these 2 that are used .
But here is where I would start to experiment .
If you edit manually with vi or make a new file and copy over with stp
.
I would rename the old file so it's still there .
And restart the radio otherwise it wont take the change .
This would be a project for a third party app ?
A code snippet with the volume maps .
Code:

-- volumeMap has the correct gain settings for volume settings 1-100. Based
on Boom volume curve

it per-device
