I still haven't solved the "thumping" problem, but I have an idea. In SH3 sounds would sometimes get stuck if the file was too long. The same is probably true in SH4. I still haven't heard it myself, but I took a look at the different .wav files, and the longest is Amb_SubmarineInterior, at about 10 minutes. You might want to replace that one with the stock version or one from another mod, and see if that fixes it.

I'm really fond of that file because of the different sounds of people whispering and coughing, and the footsteps coming and going on the steel deck, but if it's hardly necessary to the running of the game. If that's the one, maybe it has to go.
