Sony Sony XR-65A80K 65-Inch 4K OLED BRAVIA XR Smart TV ARC AUDIO FAIL Error Fix: No Audio Through HDMI ARC to External Speakers

Error code ARC AUDIO FAIL on the Sony Sony XR-65A80K 65-Inch 4K OLED BRAVIA XR Smart TV means: No Audio Through HDMI ARC to External Speakers. The TV is connected to a soundbar or AV receiver via HDMI ARC (Audio Return Channel) but audio is not passing through. The TV plays sound through its own internal speakers instead of the connected external audio device. Verify the HDMI cable is connected to the HDMI port labeled ARC on the TV — typically HDMI 3, but check the label printed next to the port on your specific model. On the TV, go to Settings > Display & Sound > Audio Output and select HDMI ARC or Audio System. Enable BRAVIA Sync (CEC) under Settings > Channels & Inputs > External Inputs > BRAVIA Sync Settings — both Control for HDMI and Auto devices off must be enabled. Set the external audio device to its HDMI or TV input. Power cycle both devices by unplugging both for 30 seconds, plugging the audio device in first, then the TV. For eARC connections, use an Ultra High Speed HDMI cable rated for 48 Gbps.
