i'm sorry for previous one, i'm ignoring the hitsound 
Problem Details:
basically a hold note on mania plays only once and it's only on hold start, but when you make the window on editor is inactive, it'll play twice instead (it means, the end of hold too).
from the beginning what i'm thinking is hold note only plays hold start, neither hold body or hold end played because it's not specified on .osu itself.
Video or screenshot showing the problem:
osu! version: 20131024.1 (latest)
