Hi Mike.

I don't use the 2D cockpit because I'm a VC only pilot (if it's available). Because of this I haven't noticed any sounds increasing when changing anything in there. I might give it a try and see if I have it happen. I do click on some of the "click points" on the OH panel so that just those gauges/knobs etc. are showing and I don't recall hearing any changes. I was really strange that the first time I installed them, I lost the seat belt, no smoking and flight attendant/captain (there might have been others) announcements.

But as I say, they are back and working and I'm very happy they are. ;D
