That's an interesting observation FDMBRZ79... I have slew key unassigned in my sim, I have no need for it, especially since it seems to mess up my FSPassengers flights if I hit it accidentally while chatting on an FSHost server.

marakab, I do get switch sounds on everything except the light dimmers, as to be expected (with the exception of the radio lights next to the rudder trim, which are not actually tied to any lights, this one "click click clicks" as you increase it.

FSX SP2 w/o Acceleration.

I did run into an interesting issue last night with the 727 though, after changing a view suddenly I had zero sound inside the cockpit.  Changing to exterior view, I had engine sounds, and switching back to cockpit my sounds returned.  This happened a couple times in this flight.  Only time I've had sound issues on the 727 at all.

If it recurs, I will use FDMBRZ79's suggestion of the SoundOffWhenSimIsSlew=0 trick.
