4. Setup Instructions
Follow these steps to set up your eSynic ESYESY266 Audio Extractor:
- Power Connection: Connect the provided USB Type-C cable to the "Power" port on the eARC Audio Extractor. Connect the other end of the USB cable to a 5V USB power source (e.g., a TV USB port or a USB wall adapter, not included). Ensure the adapter is powered on.
- HDMI Connection: Connect the integrated HDMI cable from the eARC Audio Extractor to the eARC/ARC HDMI port on your HDTV. This port is typically labeled "HDMI (eARC/ARC)" or similar. Ensure your HDTV supports the eARC/ARC function.
- Optical Output Connection: Connect the provided optical cable from the "Optical Output" port on the eARC Audio Extractor to the optical input port on your soundbar, wireless headphones, or home theater system.
- TV Audio Settings: Access your HDTV's audio settings menu.
- Enable the eARC/ARC function on your TV.
- Set the HDTV to eARC/ARC audio output (use the TV's remote control to turn it on).
- For optimal sound, ensure the TV's digital audio output format is set to PCM 2.0, Dolby 5.1, or DTS 5.1. Avoid "Dolby Digital Plus", "Dolby Atmos", "DTS:X", or "PCM Multi-channel" as these formats may exceed the optical interface's capacity.

6. Troubleshooting
If you encounter issues, please refer to the following troubleshooting steps:
"Login Only" Problem:
The "Login Only" prompt is typically not generated by the eARC Audio Extractor itself, but rather by your TV or streaming application. This usually indicates an incompatibility between the TV's audio output settings and the optical fiber's capabilities.
To resolve this, you must adjust the audio output settings of your TV:
- Enter the TV Settings menu using your TV remote control.
- Find sound/audio options (e.g., "Sound", "Audio", or "Effects").
- In the sound menu, find "Advanced Settings", "Expert Settings", or "Professional Settings".
- To modify the digital audio output format, find options named "Digital Audio Output Format", "HDMI Audio Format", or "eARC Mode".
- Do not select "Auto" or "Passthrough".
- Please manually set it to "Dolby Digital" or "Bitstream". Some TVs may display as "Dolby Digital".
Important: Please avoid choosing "Dolby Digital Plus", "Dolby Atmos", "DTS:X", or "PCM Multi-channel", as these formats exceed the transmission capacity of optical fibers and may cause playback interruption.
