I currently have a Powerbook and bought an Airport as well to connect
my computer to my stereo wirelessly.  I do not currently have an
internet connection at home, but did at one point.  When the Internet
was connected, I could play music to my stereo no problem with the
cables connected.  Without the internet connection going through the
Airport, it does not want to play music, even though there is no  need
for an internet connection to do this.  Any ideas how I can override
this?


Thanks

I take it that

1) Your stereo is connected to an Airport Express.

2) In the lower right hand side of iTunes, there is a speaker symbol
in a menu bar that shows your stereo speakers (or AirPort Express)
among other entries, such as "Computer."

3) In iTunes, if you go to "Preferences" under the "iTunes" menu, then
go to "Advanced" in the Preferences, you have a check mark in the box
marked "Look for remote speakers connected with AirTunes."

This section of the Airport Express setup guide also mentions joining
the AirPort Express network.

"You Can?t Play Music on Your Stereo From iTunes
Make sure your AirPort Express is plugged in to a power outlet, is in range of your
computer, and that you have connected the appropriate cables. You may need to join
the AirPort Express network.
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." pg. 36

If positioning of equipment and cables has changed, the following
section from the same manual may be helpful:

"AirPort Express Placement Considerations
The following recommendations can help your AirPort Express achieve maximum
wireless range and optimal network coverage.
? Place your AirPort Express in an open area where there are few obstructions,
such as large pieces of furniture or walls. Try to place it away from
metallic surfaces.
? If you place your AirPort Express behind furniture, keep at least an
inch of space
between the AirPort Express and the edge of the furniture.
? Avoid placing your AirPort Express in areas surrounded by metal surfaces on
three or more sides.
? If you place your AirPort Express in an entertainment center with your stereo
equipment, avoid completely surrounding AirPort Express with audio, video, or
power cables. Place your AirPort Express so the cables are to one side. Maintain as
much space as possible between AirPort Express and the cables.
? If you place your AirPort Express behind your stereo equipment,
place it on one side
or the other. Avoid centering it behind your stereo.
? Try to place your AirPort Express at least 25 feet from a microwave
oven and a 2.4
GHz cordless phone, or other sources of interference." pg. 40
