Water problem

[Phoroneus]

Just to clarify: you hear the splashes correctly when you walk in the water, and then after you've climbed up out of the sewer (via ladder) and are on solid ground above, you still hear the splashes when you walk? Is this correct?

I haven't run into the same issue, but a couple questions immediately come to mind:
1) What is the ground surface that is splashing after you've left the water? Meaning: is it a surface like the default castlebase floor, or is it something else?
2) Do you climb onto the ladder directly from the water, or are you standing on solid ground when you begin your climb?
...or...
3) Have I missed your meaning entirely, and you aren't talking about the player's splashing footstep sounds at all?

As I'm stuck and need a break from scripting, I'll whip up a map that should be similar to yours and see if I can replicate the problem.

EDIT: I've been trying to replicate the issue, but haven't had the same problem. Splashing water sounds when on the ground floor (flooded), ladder climbing noises when on the ladder, and regular walking sounds when on the stone floor above.
