If you use serial or BIOS terminal it will work. With GFX terminal it will result in a character instead. Other terminals the answer varies * Using play command you can play any sound but it works only on i386-pc and uses speaker/PIT. Many systems don't have speakers or they are not connected to motherboards * Using morse terminal. Same limitations as play command * Spkmodem. It's not intended for end-user sounds There's no proper way to hook up sound to described events but there're 2 workarounds: * Add \x7 to the messages, e.g. through using of .po/.mo translation * Use morse terminal.
