I just bought a Sonos arc and a LG CX 77 oled TV. I’ve noticed lately that my arc will drop audio connection when watching Netflix or any app on the native WebOS. It will drop for 1-2 seconds, revert to TV speakers, then revert back to the Sonos arc. My TV says HDMI port is now available as if the signal was cut short. 
 

my diagnostics number is 1080003327

Having same issues as others, Arc + SonyTV no configuration changes random drop outs to TV speakers , using multiple sources with same issues.sometimes corrects itself after 15-20 seconds or hardboot of all hardware required.

Hi there @peterthomas1978, Thanks for reaching out, and welcome to the community. I apologize for the late reply. I checked the diagnostic report that you’ve sent. It doesn’t show any issues with your system. It detected that the Wi-Fi capability on your Sonos Arc is disabled since you are on Sonosnet or a hardwired connection. Since you’ve done some troubleshooting steps. If the issue persists, I'll ask you to kindly contact our phone support team for further assistance and more in-depth troubleshooting steps.
