You haven’t said what type of TV it is, but as a guess, your remote is not properly set up to be using IR, something the Ray requires. Because optical is a one way connection, and doesn’t include any ARC information, the remote can’t use the ‘smart’ connection, but needs to be switched to IR. Check the TV’s manual on how to do this. Then, once that’s done, you’ll need to set up the remote in the Sonos controller area for that ‘room’

Bruce- the Tv is a Sony Bravia but the remote we use is a directv remote in RF mode.  Thank you for the help. I’ll switch to IR and see if I’m set to go. 

Just remember, once you switch the remote connection method, you’ll likely need to go back in to the ‘room’ in the Sonos controller and run the normal set up process for the remote again.
