Eric Bowen,
Now I know that you are absolutely right, The Blackmagic cards require a video signal to bring in the audio signal. So if I just want an audio input then I require a real audio interface. I think that’s the only option I should implement to solve this odd problem. I hate Blackmagic for this situation but the truth is unveiled at least. Thanks again.

No, we are not trying to capture the video (not through the HDMI/Composite/Component) in this case, we are trying only to capture the audio from our audio console through the analog RCA port of the Intensity Pro Card. In terms of ingesting/Capturing we are trying to use the BM Intensity Pro card as an audio capture device, not the video in this case.

Our Blackmagic Control Panel’s Input setting is set as “Composite + Analog Audio”. Even we have tried the “Component + Analog Audio” settings, but no input audio is found until I connect any composite or Component Y connection to the Green RCA Video input port.

So I think that the Intensity Pro Card is using the video signal to initiate the capture process, and if it can’t detect any video signal on its green video input port, it assumes that the ingest process is not required at all, which was not an issue when we were using our Matrox cards for such purpose. Thats the problem.

Chad Pearson, it would be great if you could point me some more hints, thanks.
