I just setup a new edit suite using a Blackmagic Decklink Extreme 3D Card, running on a PC with Windows 7.
Initially my 5.1 channel mapping required altering in Premier to get the correct output to the correct speakers but once sorted all worked great.... until today! For some reason no matter what I do some of the channels are now mixed up, and changing the mapping preferences has no effect. I am getting the Centre channel coming from the Rear Right and Rear Left is coming out of the Sub! I have my preferences set to output from the BlackMagic Audio Device, but even swapping left and right channels has no effect.
If I flick over to Audition and map the channels for a 5.1 mix it works fine and has the correct output which I guess rules out a problem with the DeckLink. This is REALLY frustrating me, any suggestions or advice on what could be the issue with premier would be greatly appreciated!
