Cannot control Sonos Arc volume with LG Magic Remote when TV is off

Question

I recently bought the SONOS Arc + Sub + One to use it with my LG CX tv and I configured the system along with setting up the Magic Remote.

When I just want to use the Arc without turning on the tv (eg. for playing songs using Alexa) I cannot control the volume of the Arc with the Magic Remote. Is there a way to make this work?

The volume control works when the tv is on though.

Hi @ygpatelWelcome to the Sonos Community!@Airgetlamis correct - the TV is passing the signal alongand for it to work with the TV off, you’ll need to put the remote into IR mode. You will lose some functionality on the remote if you do this, but the instructions are here on ourUnable to adjust the volume using the LG Magic Remote help page.

I suspect currently your Arc is being controlled via HDMI-CEC, from the TV through the Arc’s connection, and not via an IR signal from your remote.

If you poke around in the FAQ area, you should be able to find how to change your Magic Remote over to IR, so that it works with a PLAYBAR, which should make it work with the Arc as well, since the Arc also has an IR receiver built in.
