If there was no real vibes with the chain off and going up through the gears, I think you have your answer.
The gearbox basically has straight cut gears it's going to whine, and as the output shaft gets faster up the gears the speed the teeth wipe each other goes up.
Maybe because of the vibration you have got a bit sensative, I know it can play on the mind, I am going with sort that chain at the moment
PS - make sure that sproket is tight, and see if it's got the modified nut
