Corben Babyace no sound

I SHOULD know how to fix this but my memory is not so good .

What is the path or file that can be modified to get the engine sounds working with this excellent plane from krzysk? At the moment it is a beautiful model but without any sound.

Whoops .... sometimes it pays to read the installation instructions.

1. Copy all *.tsb files from "jungmeister" folder from your Aerofly FS4 installation path into "corben\sounds" folder.
