This is only a vague possibility - are you sure the Decklink has PCI Express 4 lane generation 2 (or better) with no other card sharing those lanes? There is a posting from 2021 (see [Post 4295](https://casparcgforum.org/t/playback-issues-with-decklink/4295)) that reported audio issues with Duo 2 which proved a lanes issue.
