Just found out that track sound of kingtiger(pz6bh) is missing
(only vet pz6bh has track sound)

anybody who wants to fix this go to
immersion overhaul sound mod->resource->set->interaction_entity->new folder

change tank_sound.inc to txt
then put this in the end

{"pz6bh tank"
{on "add_movement_sound" overload
{link_sound "move" "vehicle/tracks/pz6bh" }
{link_sound "engine" "vehicle/engine/pz6bh" }
{link_sound "engine_end" "vehicle/engine/pz6bh_end" }
{link_sound "rotate_turret" "vehicle/turret/pz6" }
{link_sound "exhaust" "vehicle/engine/pz6bh_up" }
{link_sound "idle" "vehicle/engine/pz6bh_idle"}
}
{on "gunner_hatch_open" overload
{ani_play "open2"}
}
("burn_by_engine" args 0.3)
}

save it and change back to .inc file
now it includes eingine+track sound

another tip:

anybody who wants to change the default sound of Porsche tiger(VK4501_p)
put this in the end too(skip this if you do not have tiger p)

{"tiger_p tank"
("pz6_sound")
("burn_by_engine" args 0.3)
}

it changes to tiger1 sound


I am using "robz realism mod 1.26.8" might not work in other version
