Apple Airport Express won't play WAV files

I am not familiar with your type of setup, however, I will say that I believe that .wav files are natively compatible with iTunes. Are you running 16 or 24 bit files? What is your sample rate? Where ever your problem lies, I don't think it's with iTunes.

I downloaded Air Foil after reading Chuck's post (before the other posts were made). Now I'm further away than before. For some reason, Air Foil recognizes the wireless network and the Marantz receiver, but NOT the airport express. Now it won't play anything. airport express utility still says AE is connected to the network, and Internet radio still works. I won't have much time to work on it today, so I'll report back tomorrow. BTW, before I installed Aif Foil, the AE and the Marantz would successfully play CD FLAC files (16 bit, 44.1kHz) as well as 24 bit 96 KHz FLAC files. It would not play 24/96 WAV files.

Apple Support will help. It sounds like you need someone to walk you through the situation.

Thanks for all your suggestions. I have direction to go in now. I'll be out for a few days, but I will report back when I have something to report.
