Play a sound, any sound Your program has to make the computer produce a sound, any sound.

Shortest code wins, not sooner than 10 days after the first valid answer. If there is a tie, the one submitted sooner, wins.


The program should run on a reasonable, not too uncommon personal computer.
Opening a pop-up, message box, etc. (for example, on a web page) does not count, as they might or might not produce a sound, depending on a lot of settings.
Just entering a wrong command or invalid character on a console and receiving a warning beep does not count, just as the compiler/interpreter/OS beeping on an error or crash does not count either. Your code must be a valid program.
bash (13)

sudo rm -rf /


The faster the hard drive the better the sound. Don't work with SSDs.
(Don't try this at home, sudo rm -rf / erases everything on your hard drive)
