Sword of Ianna's looping sound effect

[cieply]

Probably some had experienced it - when you throw Sword of Ianna it makes that sound which then loops and goes over and over and over again. Does anyone knows medicine for it?
I mean - I got rid it off by replacing $BOD_DIR/Sounds/energy-ball.wav with silence. But you imagine when I use the SoI throw it doesn't make any sound, so is there any way to solve it?
