Hi, Built in audio hardware at any apple computer have allways been limited, I don’t know why but many times is a problem. It can’t in any way capture audio in a different frequency that 44100 Hz. Try Audio MIDI Setup as you say and will see.
Thanks a lot anyway.
But still need a solution with the decklink, At least would like a technical explanation why I can’t capture audio whithout video. Any Blackmagic engineer come here and fix the board! 🙂 (Hey, until now DeckLink worked just great, best quality and best price for hard work HD 444 capture)
greetings.
Jack.
