Good support. Helped me to get rid of P3D and finally give up this hobby. Thanks
You REALLY "gave up this hobby" now, because you didn't like the GSX boarding sounds that has been there for years and you said yourself you know how to delete them ? Was that supposed to be a joke ?
Of course, the option to suppress them surely works. But now, given your reference to the sounds named "Boarding", it seems you are confusing two very different sound types, and the option only deals with the NEW ones ( called "audio cues" ) that give a feedback of the operation chosen.
NOTHING to do with the boarding sounds made by passengers, they have been there for years, and nowhere we ever said that option is supposed to remove those.
