I am using Windows media player 11 and when I am starting to play a song the AC3filter didn't open and nothing happened. And when I open it manually to get that message. "This utility is for OFFLINE filter configuration only! This means that you will not see any activity of currently playing applications and configuration settings will not affect them. You need to restart your player for changes take in effect!"
how can I set that the AC3 will open automatically when I open the media player?
