Sonos Beam and LG OLED C1 TV stopped working Via HDMI ARC

It has been set up and working since last October. The original setup using the Sonos App worked on the first try. I have a Fire TV connected in another HDMI port. I was working with the Fire TV remote to clear memory on the Fire TV. I lost the connection between the Sonos Beam and the TV after that. No matter what I tried the Beam wouldn’t reconnect with the TV. Thanks to every who listed here. After hours of trying, I did a search and found community. I took the advise of one of replies and unplugged my TV and the Sonos Beam. After I plugged everything back in, the Sonos App worked and connected the Beam to the LG TV via the HDMI ARC port. I am about to upgrade to the Gen 2 Beam. I hope I don’t have the same problem.

Sounds like the CEC (ARC) on the TV got “confused” and wasn’t recognizing connected devices properly. One of the many reasons that sometimes a full reload of the OS involved is helpful. Glad you were able to resolve your issue.
