Audio interface in conjunction with Decklink

Hi,

I'm trying to set up Resolve for recording using my Apollo Twin X audio interface, to handle the audio part.
And a decklink ultrastudio monitor for the output for the video. But when I plug in the decklink, I can't select the Audio interface to handle the Audio.

Any Ideas?

All the best

macOS or Windows? viewtopic.php?f=21&t=90190

when I plug in the decklink, I can't select the Audio interface to handle the Audio.

In Preferences > System > Video and Audio I/O is the Decklink set for playback use?

Once the Decklink is enabled, save the configuration and restart Resolve.
Does the Speaker Setup section then allow manual configuration?
