Had this work right once and damned if I can get it to work right now.
Audio ends up at different length to vision with major sample rate errors, even though it's flagged 16/48K.
Set all audio to Declink ASIO but that hasn't helped.
What is strange is under Options>Audio Devices when I select Decklink ASIO for the output buses and as the Device, there's no option to select the Default Recording device, this is greyed out.
