Silent Running

Silent Running silences the background music while in stealth (works for Druid Prowl also) making it easier to hear combat/stealth detection noises.

To change the level of the out of stealth sound volume just type /silent (and then a number in between 0 and 1. Default is 0.5

Or to disable the addon in game enter a 0. To turn it back on just reenter you preferred volume setting.
