Chris - Thanks for the tip! Are you using a PC or a MAC? If it's a PC, then problem solved. If not, it's still worth trying out. I'm sure I can borrow an Airport for a day.
Mark - thanks for your kind offer to test sometime. Since the card is only $25, I'll get one to try. I'm currently using an M-Audio 410 and have another home for it. If I can't get an Airport to work, I'm defaulting to a setup like yours, and will re-rip my collection as .wav or with an openly available lossless codec.
Thanks again,
Tom
