FInally I found a trick!! I usually fly with 2D cockpit, sometimes in 3D, but never use the switch on the Overhead in 3D. So, I tried to move the seat belt and smoke switch in 3D view, sounds works!! And now the best: it works in 2D panel too! I think I'v intialize something or so?? ;D ;D

Glad you got it working.

But if that's the trick you need to do to make it work for you, then that's the way it is. :-/

Mine works first time every time, and I no longer have to edit the sound.ini either. I've never needed to do the edit the sound.ini with v4.6.
