Apple AirPort Express v4.2 - Manual (Page 36)

36 Tips and Troubleshooting
Make sure to choose your AirPort Express from the speakers pop-up menu in iTunes.
Make sure you are using iTunes 4.6 or later.
You Can't Hear Music Playing
If music is playing (the progress bar at the top of the iTunes window is moving) but
you can't hear anything, check the following:
 If you're trying to play music through speakers connected to an AirPort Express, and
you've selected the “Disable iTunes volume control for remote speakers” checkbox in
the Audio pane of iTunes Preferences, make sure your remote speakers are selected
in the pop-up menu at the bottom of the iTunes window and the volume control on
the remote speakers isn't turned down.
You Forgot Your Network or AirPort Express Password
You can clear the AirPort network or AirPort Express password by resetting AirPort
Express. Follow these steps:
1 Use the end of a straightened paper clip to press and hold the reset button for one
second.
2 Select your AirPort network.
 On a Macintosh, use the AirPort status menu in the menu bar to select the network
created by AirPort Express (the network name does not change).
 On a computer using Windows 2000 or Windows XP, hold the pointer over the wireless
connection icon until you see your AirPort Network Name (SSID), and choose it from
the list if there are multiple networks available.
3 Open AirPort Admin Utility (in Applications/Utilities on a Macintosh, and in Start > All
Programs > AirPort on a computer using Windows XP or Windows 2000).
4 Select your AirPort Express and click Configure.
