I’m working through an issue where RoonBridge is connected to the wrong mute control element, and this results in the mute control having a problem.
Looking at the logs of RAATServer (/var/roon/RAATServer/Logs/RAATServer_log.txt), I see this:

The correct element is “Power Amplifier Mute”.
/var/roon/RAATServer/Settings/device_ce64659de8b97996bd2dbded0fbc97f9.json looks like it is the intended configuration file to use, but I do not see any documentation on how to use it in the knowledge base, the downloaded packages, or this online forum.
Is the documentation available?
Cheers,
Jon
