function plugdetect(plugName) 
{
         if (navigator.plugins[plugName]) return true;
         else return false;
}
Use an if statement similiar to this one combined with the above function to detect plugins, putting the plugin name in place of "LiveAudio": 
        if (plugdetect("LiveAudio") == true)
        document.write("have the LiveAudio plugin");
        else document.write("do not have the LiveAudio plugin");
