@Boris_Pruessmann I’m facing an issue when using your extension as External Source Control within the device setup. Turning on/off the amplifier works well but Roon will not play any music, the track does not start. Removing the External Source Control will allow the music to play again.
Defining the External Source Control provides on/off functionalities for the amp:
As far as volume control, it works well without and with the External Source Control defined.
My amplifier is a Marantz NR1606.
Any help would be greatly appreciated!
Thanks
