How do I turn off or change the default alert sounds in Xfire?
You can easily turn the sounds on and off by going to the Tools | Options | Sounds tab. From this menu you can select specific sounds to turn on and off. If you want to manually change the sounds, navigate to your default Xfire directory and go to the Sounds folder. For Windows Vista users see here: http://www.xfire.com/faq/#228 By replacing the .wav files in that directory with your own files, named to match the proper sound event, you an customize your Xfire sounds to whatever you like. We’ll be adding in the ability to customize the sounds from within the client itself in the future, but you can do this manual change anytime.
