After lots of messing about and many driver attempts I have figured it out!!!!!!
It was a conflicting driver in the audio, disable all drivers and enable them in a different sequence and behold 'There was sound!'
I think the cause was the order windows in its glory downloaded them automatically in the wrong order causing the hdmi output to be the primary.
This amount of messing about came about when all hope was lost I tried running from a ubuntu boot disc and sound was instant.
