Interesting, i use Z5500s and can hear sound in the GT5 demo fine. What boxes did you tick when you enabled optical out? I just tick the top set (up until the box ticked by default) then leave the ones below that unticked.
Same.
pm sent let me know if you have any problems
I REALLY appreciate it mate, do you mind if I wait until after I go see avatar (in 25 minutes so better dash!), do you want stardust/tekken 5 in return?
