Cara, I am running CS6 on a PC. I send HD-SDI video out of the Kona 3 card to a Panasonic engineering monitor. I take the analog audio out of the Kona 3 breadk out box and send to my speaker preamp which outputs stereo to studio speakers. I am running the 2 most recent AJA drivers on my system. I get NO delay between the playback on Premieres timeline montior and the external montior. It works perfectly.
I share that as an example of what you desire being possible with CS6.
