When changing the sound output while beeing in game (f.e switching from loud speakers to headphones and back), FAF does not change the output setting and becomes mute.
Also there´s a quite annoying, very loud sound effect when you close the game.
It is an old game - I'd recommend to switch before hand. There have been numerous issues regarding sounds (stereo vs 5.1, etc) and there're all of the type 'unfixable' as they are related to the engine.
