Depending on your setup you could just use six analogue connections to your amp.but thanks anyway. Is Win XP still an option for now and the foreseeable future because i think it doesn't have the mentioned pin-problem.
I had a fair few problems with XP a few years ago (Which I think was a combination of the Xonar HDAV soundcard and Onkyo receiver) . I ended up buying a HDMI Detective which is certainly not cheap but I have never had any HDMI issues sinceYes I have and I had every problem one could have with Hdmi on Win7
