1) after I renamed the file 33211B8E7F131384F50DAA36062F4027E13D70E8 my character has ceased to utter any sounds. so that is right file with sounds.
2) Then I unpacked the archive and put all the files evy_ *. wav in the directory Vindictus\en-US\sound
but the character still does not utter any sounds
Wondering whether to pack those sounds in the hfs file? I think if I'll edit hfs file, all probably will work, as needed. But how to edit? Is there any soft for that purpose?
while made this post I found salvation for those who will stuck as me

is needed to create folders
sound\voice\pc
and place the wavs exactly to pc folder
for editing embedded textures and music I found VZipFlip6
nice tool, google will help you find it, if you are interested in it
