When operating the aircraft doors either by themselves or from the tablet some doors have opening 'clunk' noises, but will oddly stay completely silent when closed. One or two are correctly modelled and do make noises both opening and closing (for example, the pilot's window hatch, and one of the two emergency exits). 

There are more examples than I can attach as screenshots to one post so examples of which others do not behave correctly, will be in replies underneath. 

1. The engine baggage doors open with a lovely ‘clunk’ but make no noise at all when closed. Would be nice and not so immersion-breaking on a walkaround. 

2. The ‘secondary’ side door to the left of the main exit door is silent when opened or closed, from inside or outside the aircraft.

3. The nose hatch(es) open with sounds but close completely silent.

Whoops. Sorry about that! Not sure how we missed it. 

We've resolved this issue internally and will fix it in an upcoming update. Thanks for pointing that out 🙂

Is it only me but the engine sound on cruise is excessively high? Have you considered implemented a headphones simulation? That would be very convenient.
