My goal is to be able to play Dolby TrueHD and DTS-HD Master from Bluray iso (3D and 2D)and mkv from my PC to my samsung HDTV. at the moment I am using Asus Essence ST and coax cable to Onkyo SR805 for sound and hdmi from GTX 570 to TV. I understand that I cannot get HD audio through Essence ST (coax because of bandwith and analog surround because of PAP), and my GTX 570 soes not support bitstreaming of HD Audio.
I am now looking at Asus HDAV 1.3 and want to know whether it will be the best choice? I am only going to send audio to my avr, video will go through gtx 570 because avr does not support 3D bluray passtrough. Will there be any problems doing this with HDAV 1.3 card using hdmi? Will using analog with HDAV 1.3 (I have H6 board) to Onkyo SR805 prevent me from using Audyssey vs using HDMI?
