My SONOS ARC has been very unstable for the past 3 months on my LG OLED CX tv.
Every day when I turn the TV on, there’s a 50% chance of the TV reverting its audio output to the internal speakers.
Tried a different cable and tried to disconnect every other device. Tried to reset the SONOS and the TV, all without luck.
Diagnostics 679505560, the issue happened within 2 minutes of this diagnostic report.
