I have a 9 month old LG 4K Smart TV and a Sonos Beam (as well as a Cable TV Box). Everything was working great for the past 6 months (Sonos using HDMI ARC). Yesterday, we lost power for less than a minute and now the Sonos cannot maintain a connection to the TV. Specifically, when watching TV, the sound will come through the TV speakers, then switch to the Beam for a second or two, and then back to the TV. I checked all the TV settings and SIMPLINK is ON and whenever I try to set the Audio Out to HDMI ARC, it only stays set for a second or two and then automatically switches back to “Internal TV Speakers”. Tried rebooting Sonos several times as well as turning the TV ON/OFF.
