Guild Wars 2

I am experiencing a sound issue whenever I equip my exotic armor chest piece, which is an emblazoned coat (leatherworking) transmuted with the Order of Whispers coat appearance. Here is the issue.

If I wear any other chest piece I have no problem, but if I switch to the whisper coat and then equip an engineer kit (ie, flamethrower) then suddenly I get a constant effect of what sounds like coins jingling whenever I move. This sound persists if I switch to a different coat, but stops if I then equip an engineer kit again and doesn’t return until I switch back to the whisper coat. The sound also occurs if I log into the game while wearing the whisper coat or waypoint to a new area while wearing it, and is removed the same way (switching armor then using a kit), but does not occur while swimming in water (on surface or below).

This is probably a weird issue, but it’s really annoying to me, especially in Lion’s Arch. Is there something I can do to identify and fix this? Emblazoned coat isn’t supposed to jingle or anything, is it? >_>;
