When I am fighting and I pause the game, if I do so during some attacks the sound will play over and over again until I unpause.

I get this when I'm in slo-motion.

I get it when pausing before a stun.  No slow motion required.

I also get this when fighting the wolves immediately south of the starting point for Dyrwood Forest; the prone sound seems to play multiple times when paused.

The Knock Down ability still does it after you pause during the middle of a fight. An enemy used knock down on me, I paused and it looped 3 times. Then I used Knock down on my Fighter, didn't pause, but the sound looped 3 times.

I've also had this happen. Also sound related, sometimes the in game sounds just stop playing but I still get music.

Getting this as well, get the same "whump" sound over and over during combat. Pretty annoying!
