Unfortunately it is difficult to determine the issue from the description. But is it possible to capture 4 inputs on the DeckLink Duo 2, you can run QuadPreview SDK sample to check this.
I am assuming that you have set both devices bmdProfileTwoSubDevicesHalfDuplex profile and that your code is:
- iterating through 4 instances of IDeckLinkInput
- calling IDeckLinkInput::EnableVideoInput on all inputs
- calling IDeckLinkInput::SetCallback on all inputs, referencing your IDeckLinkInputCallback class
