Adium script that can mute the system volume completely free of charge.
One of the best features of Muter is that you can add its command to your away messages. So, when you step out of the office or room, you can rest assured that your system volume will be turned off. All you need to do is enter the "%_muter" command in the active message window and voila!
It's worth noting, though, that you'll need to enable the volume manually when you return. And if you happen to have your Away status still active, the system volume will be muted again during Adium's periodic status update. Overall, Muter does what it promises and takes the worry out of remembering to mute your system before stepping out. Highly recommended!
