Look at the CrashDive (Submarine_CrashDive_INT.wav - under 14 secs in FotRSU) sound file. If it's the one with the "bell" clanging, that will be the problem file. I'll look into the regular "Dive" file for FotRSU, but we haven't had issues (other than speech) since we changed the CrashDive and shortened the "Creaks" files to less than 15 seconds... wait - there were a couple of other files that were over 15 seconds... I don't think I have my notes for that any more either, since I had a catastrophic HD crash a couple of months ago, and lost a ~LOT~ of my modding files...
The "Dive" has 3 files in FotRSU, all under 15 seconds. There is the 'valve' noise in "Dive sequence.wav", waves lapping in "Submarine_diving.wav", and the actual dive alarm a "Dive!" in "Submarine_DiveAlarm_INT.wav". You might be describing the original FOTRS file(s), which were too long fershure fercertain...
