Try disconnecting everything from your TV and unplugging the Beam and TV from power for a couple of minutes. Plug the TV and Beam back into power but leave the Beam and any other device disconnected from the TV. Be sure Simplink (CEC) is turned on and eARC is turned off in your TV settings. Perform the TV Setup process in the Sonos app and connect the Beam to the TV’s HDMI ARC/eARC port when the app instructs you to. When the Beam is connected and working correctly, connect any other devices to your TV.
If this doesn’t work, try the same process with eARC turned on.
If that doesn’t work, you may have to connect the Beam to the TV with the optical adapter.
Hi @dawson8321
Welcome to the Sonos Community!
What @GuitarSuperstar said, but with the addition that with an HDMI connection in use, there is no need to program Sonos to recognise your TV remote. This is only needed if you are utilising the optical adaptor to connect the Beam to your TV.
Additionally, as @GuitarSuperstar alluded to but didn’t say outright, another device connected to your TV may be causing CEC conflicts on the HDMI network. Be sure to test things with only the Beam connected to the TV, and we can move forward from there.
@Corry P @GuitarSuperstar it actually worked by disconnecting everything.. dont know how or why but it worked by plugging everything back in. Many thanks for your support guys!
