I don't know if this has been asked before, but it's really grating.
In 1.2.5.0, I installed a fresh version of skyrim and enderal for this update. The sound when you jump in the water, the splashing sound, now plays at random intervals, consistently in my game. It sounds like the sound file is playing 3-4 times in very fast succession, then stops, and this happens anywhere on the map (I think only outside though), and can happen very frequently. Not sure how better to describe this bug.
It may also be the sound it makes when diving underwater, because sometimes when it happens a blue filter splashes over the screen, like when you dive underwater.
(Also, not sure if this should be here or in the bugs section, sorry if it's in the wrong place)
