I noticed that there is two folders in captain sim folder L1011-1 and L1011 I tried to move the 1011 to 1011-1 that removed all the sounds from the cockpit but I got some callouts so I reinstalled the aircraft and looking for a better solution, if someone had the same problem and mange to solve it?

Make sure the sound.ini file from the v-one package that goes into the captain-sim folder in your root prepar3d folder is edited as it points to a folder that no longer exists if you are using the latest version of the tristar for P3D4/5. (1011-ii)

In the sound.ini file from V-one
Edit the line under [common] from
Sound.Directory=Captain_Sim\1011\sound
to
Sound.Directory=Captain_Sim\1011-II\sound

This maybe why you have no sounds

install all of the sounds from the v-one package into this folder
Captain_Sim\1011-II\sound
not
Sound.Directory=Captain_Sim\1011\sound
