When I used to have Vista it was a simple case of opening one bit of software and then changing the default audio output on control panel.
What I am trying to say is that I want to use sound on my dual screens each with its own sound i.e if I play a movie on screen 1 I want the built in speakers to have the sound of the movie.
On screen 2 I may want a game with its own audio output.
Is there any simple way of doing this? As I say I got it working with Vista as it only changed the sound output for software not in use i.e so as long as I had the movie on and didnt close the player it outputted fine.
