Creaking hull sounds gone?

[U-boat luver]

I've been really enjoying SH4 on my computer since I got it from a friend a few days ago. With all the patches and TMO 2.2 its great and has wonderful immersion. One thing I notice though is how the creaking sounds from the hull as my submarine goes deeper and deeper in the water seems to be gone. In SH3 I had all sorts of creaking sounds that came with mods and from vanilla but now in SH4 the sounds are gone. Am I missing something or have the creaks been removed in SH4?

If there are no creaks in game by default could a mod be possibly made to fix this? Its really great for immersion and I think its just awesome to hear while diving.
