[ANSWERED]Airfoil not working through Airport Express

Indigo seems to work fine when I direct speech through any Mac speaker on my Ethernet network. I have a couple of Airport Express units, also connected to the network via Ethernet. Each of these has a speaker connected to them. When I try to have Indigo direct speech to either of the Airport Express units, the speech is never heard/played, although the trigger to play the speech is firing. It's not a volume problem. Any Indigo or Airfoil tips to get the Airport Express speakers playing?

That did the trick, thanks.
