Make sure the sound.ini file from v-one that goes into the captain-sim folder in for root prepar3d folder is edited as it points to a folder that no longer exists if you are using the 1011-ii.

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
