Sony Sony STR-AN1000 7.2-Channel AV Receiver with Dolby Atmos DECODE ERROR Error Fix: Audio Format Not Supported / Decode Failure

Error code DECODE ERROR on the Sony Sony STR-AN1000 7.2-Channel AV Receiver with Dolby Atmos means: Audio Format Not Supported / Decode Failure. The receiver does not produce audio and may display an indication that it cannot decode the incoming audio stream, or the receiver plays only stereo when surround sound is expected. The audio format being sent by the source device may not be compatible with the receiver current listening mode or settings. Try changing the audio output format on the source device to PCM (uncompressed stereo), which is universally compatible, to verify the receiver and speakers are working. Then try Dolby Digital or DTS formats, which are widely supported. Check that the receiver listening mode is set to Auto or a compatible decode mode for the incoming format (for example, if the source is sending Dolby Atmos, the listening mode must support Dolby Atmos decoding). Bitstream audio from streaming apps on smart TVs sometimes uses audio codecs that require specific receiver settings or are only passed through correctly via eARC rather than standard ARC.
