Blackmagic Decklink Duo not recognized at startup

Hi there,

I have a problem with the FMLE 3.2 on Win8.1 and a Blackmagic Decklink Duo.

The Decklink is working well with other software, e.g. Windows Media Encoder.

But in FMLE there are some issues. I can set the video input to Decklink Video Capture and the audio input to Decklink Audio Capture without any error messages.

But when I´m saving and reopening the saved settings, I´m getting the error message "Problem with audio capture device. Profile specified the device: Decklink Audio Capture Selected default device: Decklink Audio Capture (2)"

Now, Decklink Audio Capture (2) is selected, but the volume bar is gone and there is no audio recording.

So, there is no way to run the FMLE with a script because in every situation, there is an error. Maybe it has something to do with the Mainconcept AAC encoder?

I uninstalled it, but same errors. I have two machines, same problem on both machines, so I don´t guess, this is a hardware error.

any ideas?

Thanks in advance
