Troubleshooting
No audio output
Verify all audio cable connections. Ensure the correct audio output port (Optical, L/R) is used and connected to the appropriate input on your audio device. Check the EDID switch setting on the extractor. Confirm the audio source device is outputting audio via HDMI.
No video output
Ensure the HDMI cable connecting to the display is secure at both ends. Check if the display is set to the correct HDMI input. Verify that the source device is outputting video. Confirm the extractor is receiving power.
Poor audio/video quality (stuttering, artifacts)
Try a different, high-quality HDMI cable. Ensure the HDMI source and display support the selected resolution and refresh rate. Check if the USB power source provides sufficient power. If using multiple devices, ensure they meet the specifications.
CEC control not working
Ensure CEC is enabled on both the source device and the display. Verify that the CEC pass-through setting on the extractor is correctly configured (if applicable, though this model implies pass-through is always active). Test CEC directly between source and display without the extractor.
