Strangely my ai traffic sound seems to have stopped working, but just when ai a/c are taking off. Previously you could sit in line waiting to take off and you'd get a definite roar from each a/c as it begins its full thrust takeoff roll, but now they seem to be quiet as a mouse!Other sounds from them seem to be fine - startup spool, in flight, taxiing etc - just not that satisfying takeoff roar. Any ideas? I'm aware from reading posts that a/c have 'sound cones' so perhaps something has been altered and they're not correct? Or perhaps a missing sound file? I've looked at the sound.cfg files in the SimObjects folder and they seem to reference an alias I can't find, so perhaps that's it?This is all with JustFlight's Traffic X. I have tried re-installing but to no avail.
