What happens is if you choose the Alarm sound to be "Beep", the iPod will beep from its internal beeper/speaker. Very unfortunately, in only beeps for about 2 seconds and then goes off. That is entirely not acceptable because a 2 second beep is not going to get most people up from bed. In the next firmware update, I hope Apple enables a longer beep. Not all of us have speakers connected to the iPod when we sleep. I sometimes have my earphones on and then fall asleep. And of course, in the morning, the earphones are nowhere near my ears.
