When you activate the Flight Engineer on the 2D pop-up, do you get any kind of audio acknowledgement, as in "Preparing systems now" etc?
When you first enter the A/C, do you get any audio from the other members of the crew, as in "Morning Captain" etc?
What happens when you select the various passenger loads from the 2D pop-up, any audio played then?
What happens when you select "Cold Start" from the 2D pop-up panel?
If you're waiting for the FE to start the engines, then it'll be a long wait; the FE will not start the engines for you, that is something that you have to do yourself.
Worry ye not, help will be forthcoming
