1) PCM tuning method: Menu - All settings - Sound output - Optical - Digital audio output - PCM
2) If you need to synchronize the audio output of your TV's audio system: Menu - All settings - Sound output - HDMI ARC
4.5 Enabling CEC Function (Optional)
If your TV supports HDMI-CEC (Consumer Electronics Control), you can enable it to control the volume of the connected audio device using your TV remote. The specific setting name may vary by TV brand (e.g., LG Simplink, Samsung Anynet+).

The high-fidelity sound output is suitable for various audio experiences, including music, movies, and gaming.
6. Troubleshooting
If you encounter issues, please refer to the following troubleshooting steps:
- No Sound Output:
- Ensure all cables (HDMI, audio, power) are securely connected.
- Verify that the HDMI cable is connected to the HDMI ARC port on your TV, not a standard HDMI or eARC port.
- Check your TV's audio output settings. Confirm that the audio output is set to PCM stereo and not Dolby Digital or DTS.
- Ensure your external audio device (speakers, headphones) is powered on and correctly configured to receive input from the 3.5mm/RCA connection.
- Test with a different HDMI cable or audio cable if possible.
- Poor Sound Quality:
- Ensure the USB power supply is stable. If using the TV's USB port, try a dedicated 5V USB power adapter.
- Check the quality of your audio cables.
- Verify that your TV's audio output is set to PCM.
- TV Remote Volume Control (CEC) Not Working:
- Ensure CEC (e.g., Simplink, Anynet+) is enabled in your TV's settings.
- Some TVs may require specific CEC settings or may not fully support external device volume control via CEC. Refer to your TV's user manual for detailed CEC functionality.
