hi,
excuse me for wrong info.
i have decklink extreme card, using 5.6 drivers and v7.0a.
didn’t try 5.7 yet.
if i’m right, vegas now directly comunicate with dl card, not trough dl’s control panel as it was with 4.8.1.
so, analog i/o is not supported in vegas yet, analog monitoring works for me and it should work for you.
i try to find some info about multibridge and vegas many times but with no luck.
i don’t know is it even tested by blackmagic or sony.
regards,
gordan
