Eisenhouwer, thanks for your reply.
Yes I do have the latest module system. I don't ever use it, though, as I find the unofficial troop and item editors much easier. The reason I used it last night was because I was trying to cover all bases, including the possibility of an error on your part with the text file (I figured you might have gotten it mixed up and placed an older test version into your release folder, so running your module_sound.py would for sure give me the right one). As it stands, there was no error on your part. So ... base covered.
Here's a breakdown of my mod, just so you know what it is/does....
I started over the core files of the Polished Landscapes mod and built from there. I then incorporated the Banner and Flag Standardization Pack. I added my own custom resource and textures which also includes many of my favorite community weapons and armor. Finally, I've added custom troops and a new troop tree.
So, aside from the files that are changed by Polished Landscapes, as you can see, this is essentially the Native mod with new item_kinds1, troops and party_templates files (and a modified ini, of course, to account for it all). Nothing else has been changed. Which begs the question, how can I get your mod to work properly when it's installed into an ACTUAL Native mod, but not my own, which is just a slightly modified Native mod?
Could Polished Landscapes be incompatible? And if so, how?
EDIT: Of course I've been running the earlier version of COW along with Polished landscapes all this time with no issues, so I don't see how the new COW could cause problems.
EDIT 2: Definately not Polished Landscapes. I tried it out on an earlier version of my mod without PL and still had the messed up sounds. In fact, I threw the files into Native and low and behold, the sounds were still messed up (which is a step backward from my brief success last night). I've checked, double checked and triple checked to make sure I'm installing it correctly. Installation really isn't that complicated, so I'm stumped.
