I know this has been beat to death a bit, but maybe this is a bit different. We got a TCL 65R625. We have a Sonos Playbase. We set up the TV, went through the Sonos App as always, Volume up, detected...Volume up three times, good. Volume down three times...good. Mute...good. Sweet, that was easy. Roku Remote working perfectly with Playbase.
The TCL batteries that came with TV ran out. Switch batteries in Roku remote, and Playbase would not respond. Went through process again, and now the playbase won’t detect the Roku remote. So it WAS working perfectly. Now it cannot. I called Sonos and after 25 minutes of “ok, hold please…..thanks for holding...try this...nope...ok...hold please….thanks for holding...try this” I gave up. Using old Samsung remote works fine, but would love to just have Roku remote if anyone has experienced this.
Again, it DID work for the first few days. Now it won’t.
