The package uses aliased sounds meaning it uses sounds from another aircraft, which you must have installed.
In this case it uses sounds from the UKMIL Tornado shared files base pack available here-
http://www.simviation.com/1/browse-Military-57-12?mark=35341#35341You can alias sounds from any suitable aircraft that you have installed by editing the Dutch Viper's sound.cfg files. Example:
The Dutch Viper sound.cfg file-
[fltsim]
alias=UKMIL Tornado Shared\sound
To use the default Lear 45 sound, change to-
[fltsim]
alias=Lear45\sound
or any other aircraft's sound-
[fltsim]
alias=any aircraft's main folder name\sound
