Under the HDMI connection sub menu on blu ray player there was a 'hdmi audio output' option.
Feel a bit stupid now lol
No, do not feel like that. Technology these days is becoming so complicated that so many people these days are having problems with it. I have a ten speaker home cinema system which took me ages to set up, wire correctly and adding 5 DVD players as well as a Sky HD Box, so you can imagine the problems I had.
Next week I am adding a Tivo Box courtesy of Virgin, so that will take some faffing on to get that working.
