Can anyone think of any reason why I get  no VC sounds

I have done everything on the KB#1094, move the .dll to fsx folder edited the sound cfg.

Nothing makes the sound for the cockpit work, the same with the 767.

Running W7 64

Sound card has the very latest drivers and i tryed turning of all EAX etc but nothing.
Sent CS a ticket and they rejected it :-X nice  :(

Anyone got any ideas?
Many thanks

Dave.
