Hi,
Hopefully someone can be of some help out there. I use a Blackmagic design Decklink card in PCIEX4 on the Z390 motherboard Big Sur 11.4. Everything has been working fine, now all of a sudden the Desktop Video Setup can no longer see the card.
Have checked if it was an EFI problem - definitely not as far as I can tell.
Have checked with my back-up disk which is on Big Sur 11.3.1 and the Decklink card is recognised and everything is working. Both with current EFI (0.7.1)and previous EFI (0.7.0)
I did notice about a week ago there was an automated Blackmagic Design update but for what reason, I have no idea.
I tried uninstalling Desktop Video Setup then reinstalling but no luck.
Any suggestions?
