There is no documented origin for the 'Aprivate' sound: it was uploaded to a user-generated soundboard under that unexplained title, with no artist, tags or ID3 metadata identifying what the clip contains or where it came from. Cryptically named uploads like this occasionally catch on as inside jokes inside small friend groups or niche communities, where the meaningless title itself becomes part of the gag. Nothing about its history can be confirmed, so it is best treated as an anonymous web upload rather than a clip from any known show, game or creator.
