Ever since the first patch I have occassionally had a sound repition bug, the sound is the sound effect for a standard jump and it will repeat every few seconds until I enter a building, anybody else have this issue?

Yeah, I've had it once. But considering the many annoying sound repeating bugs called "NPC's" it's not something I worry about.

I haven't had this issue at all. I've had some sound effects get backed-up for a few seconds (that is, i do a few actions where no sound plays for them, then after a few seconds they all play at once). Not a big issue.

The other I've experienced is with some enemies that have been using a restoration spell on themselves. Sometimes the sound will keep playing around their body even after they're dead.

What platform are you on? (X360, PS3, PC?)

I've had that bug too, but I don't think I've had the second one you had and I'm on PC.

to be honest first time I heard it my old Crysis 1 kicked in and open console typed s_soundenable 0 s_soundenable 1
