Hi there,
I have another situation where the embedded audio of my SDI signal leaving the decklink becomes garbled after several hours. According to Vmix support this is happening quite frequently with the Decklinks.
This is the external output of Vmix - restarting it does fix the problem but I need a continuous signal. All other audio outputs within Vmix are fine - including streaming, recording, etc.
So it seems to be about the decklink. I tried different models, so it seems to be a general issue. I once had the same issue with a Decklink Duo II in an external Thunderbolt enclosure from Sonnett and it could not be solved.
Then it seems to be specific to the devices that carry the card. I have some other PCs that playback fine.
Any ideas anybody?
