If there is no audio in recording or stream:
- Confirm the VC-8KTUSB3 is selected as the audio input device.
- Check the microphone or line-in connection.
- Check OBS audio settings.
- Confirm the source device is sending audio.
- Use Monitor and Output in OBS if audio monitoring is needed.
- Try PCM stereo audio for best compatibility.
EDID Requirement — Critical
Use the EDID dial switch to control source output behavior.
| EDID Mode | Use Case |
| COPY | Use when a loop-out monitor is connected and you want the source to follow the monitor EDID |
| 8K | Use when the source and system need 8K HDR capability |
| 4K | Use when stable 4K60 4:4:4 capture and monitoring are preferred |
If there is no video signal in capture software:
- Try switching EDID mode.
- Reconnect the HDMI source.
- Reconnect the USB cable.
- Power cycle the source device.
- Lower the source output resolution.
- Try 4K EDID mode for compatibility.

Understanding the Application Example
The application example shows a Blu-ray player connected to HDMI IN. HDMI OUT connects to a monitor for loop-out viewing. The USB-C port connects to a PC for capture. MIC IN connects to a table microphone, LINE IN connects to an external audio source, and LINE OUT connects to speakers.
This shows the main use case: HDMI video and audio are captured by the computer while the same HDMI source can be viewed on a monitor and external microphone or line audio can be integrated into the capture workflow.
