Is the decklink audio drift issie getting looked at? Not seeing a lot of action here on fixes or even responses.

A number of reports are now in the list citing the decklink audio drifting out of sync
not related to dropped frames as some cite the reason for, since some are not
using streaming.

I'm dead in the water with this happening. It should be a cinch to reproduce.

Please someone give us an idea, its looking bleak due to seeing a lot of 0 replies on this forum.

Hi !

The only thing I found to solve the problem at the moment is to use an audio embedder (Like the Audio to SDI blackmagic ones) to have both the audio & video sync. I didn't find any software solutions at the moment. Since it's only the audio that drifts but not the video it works perfectly.

Typically what I do is plug the Focusrite Line Outputs into the Audio Embedder along with the Decklink SDI Output.
Have been running a test for two days with a high GPU & CPU use and there's still no audio drift so it seems to work.

I'm still hoping for a fix but it works !
