Some progress.

Opened up the Din Comms plug from the reviver - the wiring did not look as I would expect from the wiki here - red wire going to pins 3&5, ground to pin 2 and a blue wire to pin 1.

Unsoldering the blue wire from pin 1 allowed Din comms to work - Roon can wake the speaker and control the volume smile

Tried moving to the BNC comms input with the Din to BNC adapter and comms fails to function - will check the wiring of the adapter.
