This a mystery!
After a lot of trial and error and help from Sonos Tech Support, I got the LG Magic Remote to operate my Sonos Playbar so the TV sound comes through the Playbar and volume can be changed with the remote.
Then I disconnected the Playbar from the TV to put the TV on a swivel stand. When I reconnected both devices, the Magic Remote no longer operates the Playbar. I followed exactly the same steps as before .. but no luck!
Any suggestions are most welcome !
TV: LG 50UN7300PTC. Purchased April 2020 - new model
Sonos Playbar
Connected via optical cable.
Steps:
1. Connect Playbar to TV. Several ways to access this function, I clicked Set Top Box icon at top of remote next to power button. Followed steps to add PlayBar via optical cable, selected Sonos from list of brands, and TV screen confirmed Playbar was successfully connected. In Sound Out on TV, chose Optical.
2. Disabled two LG Sound Out functions - SIMPLINK and LG Sound Link. (This was the crucial step first time around)
3. On the Sonos app on mobile/tablet, Settings/System/Playbar/Add Remote control and followed steps to pair the Magic Remote with Playbar. NOTE: This only worked when TV was OFF as this forces Magic remote to use Infrared (Playbar only recognises IR, but Magic Remote uses Radio Frequencies when TV is on. (It no longer uses Bluetooth). Turning TV off activates the IR.
***Despite all settings being the same as previously, now when I press volume controls on Magic Remote, the NULL sign appears on TV screen and Magic Remote no longer controls the Playbar. The Sonos app can still be used for Playbar volume control.
Any ideas?***
