UltraStudio 4K + DeckLink: How to choose SDI audio channels?

Hi Members,

We just switched from Osprey 700e HD video capture cards on PC to UltraStudio 4K and DeckLink cards to Mac using Flash Media Live Encoder as well as Telestream Wirecast 5 for live streaming and ran into a really serious problem. The driver doesn't seem to make the audio channels selectable. It rather seems that there are just channels 1&2 stereo or a downmix of 1&2 mono available what is totally unsuable for most of our events.

The most important requirement of most webcasters we know is to webcast in several languages (which are represented as several SDI channel - be it live on site or via satellite) - especially in the EU (at least english and national language) or Canada (french and english) or other multilingual countries like Switzerland or Belgium.

Could anyone help or confirm?

Thanks,
Tim

How are you getting audio into the card? Is it embedded into the video signal? That is the only way to get more than 2 channels as far as I know (at least on the Ultrastudio 4k)
