Is the environmental water sound corruption in the Panama Canal Mission, wich my comrades and i face since month a common thing?
If it is a common thing, maybe this work could help.
I unpacked the "resources-0023.pak" from the "gamesdk" folder into the "gamesdk" folder using the 7-zip program like previously mentioned.
Then i deleted the original resources-0023.pak.
When unpacked there is a folder "sounds" and in that is one called "environments".
Here the file "amb_ocean_water.fsb" seems to be the origin of the sound corruption.
I renamed it to "old_amb_ocean_water.fsb"
Now i can hear the rain and other sound crystal clear.
