Help me with Edius and Decklink Micro SDI

We have for video editing software the Edius Pro 9 and i have Blackmagic Micro Sdi card for output. The problem is when i hit Space for playback from timeline i have aprox 1 sec delay to audio. If i pause in Bsplayer a movie, and i come back to Edius, but Bsplayer is in background, Edius plays ok the file without delay. My blackmagic card i see in the Settings menu and i can select like output. With Media Express from blackmagic is working ok, but with DaVinco Resolve is the same situation with 1 sec delay of audio. I have putet drivers with 10.10 and the latest 11 but the same problem.
I dont have solution for it, please tell me.
