Internet Sharing and AirTunes at the Same Time?

Question

I've seen similar posts on this question, but none exactly on. I think I have a fairly basic situation.
I'm using my G5 as a base station to broadcast Airtunes to another room. G5 is connected to the Internet via cable modem. Using Airport Express as receiver.
Now, I just bought a powerbook and want to use the G5 for wireless internet access by the PB. But when I turn on internet sharing on the G5, it seems to cut off/shut down the airtunes network. Airport icon looks quite different. Conversely, when I get the airtunes working, the sharing can't be turned on.
Anyway to sort this out so that I can run both at the same time?
thanks

I believe, in theory, you should be able to do this. I am assuming from your description the G5 is connected, via Ethernet, to the cable modem and you want to use Internet Sharing to use it's wireless to commuicate with both the AX and the PowerBook. I think if you set up Internet Sharing and add the AX as a "wireless client" this may just work.
Let's double-check your settings...
To setup for Internet Sharing (Wired to Wireless):
Enable Software Firewall
System Preferences > Sharing > Firewall
- Click Stop to start the software firewall
Setup the Network
Cable Modem > (Ethernet cable) > [Ethernet port] Mac_#1 > (wireless) > Mac_#2
Setup Port Order
System Preferences > Network > Show > Network Port Configurations
- Verify that "AirPort" and "Built-In Ethernet" are enabled.
- Verify that "Built-In Ethernet" is at the top of the list, followed by "AirPort".
- Click "Apply Now."
Configure the Internet Connection
System Preferences > Network > Show > Built-In Ethernet > TCP/IP
- Configure IPv4: Using DHCP
- Configure IPv6: Automatically or Off
Enable Internet Sharing
System Preferences > Sharing > Internet
- Share your connection from: Built-in Ethernet
- To computers using: AirPort (checked) (Note: Uncheck all other entries in the list.)
- AirPort Options
-- Network Name: <anything you want>
-- Channel: Automatic
-- Enable encryption (using WEP) (optional)
-- Password: (optional)
-- Confirm Password: (optional)
-- WEP Key Length: (optional)
-- Click OK
- Click Start
To set up AirTunes on the AirPort Express Base Station (AX), using the AirPort Admin Utility, connect your computer directly (using an Ethernet cable) to the Ethernet port of the AX, and then, try these settings:
AirPort tab
- Base Station Name: <whatever you wish or use the default>
- Wireless Mode: Join an Existing Wireless Network (Wireless Client)
- Wireless Network: <select the Internet Sharing wireless network>
Music tab
- Enable AirTunes on this base station (checked)
- Enable AirTunes over the Ethernet port (optional)
- iTunes Speaker Name: <whatever you wish>
- iTunes Speaker Password (optional)
In iTunes:
iTunes > Preferences... > Advanced > General
- Look for remote speakers connected with AirTunes (checked)
