Ohhhh, didn't think about the Mac implementation. So, you were able to _make_ a recording but you can't play it back, right? It still sounds like a settings problem....
What about streaming a ripped CD to it? ASIO is a pretty common software interface used to get around the lack of standardization found in Windows. I'm not clear that it is used on Mac systems. I'm not going to be able to help that much on Macintosh platforms.
Also, have you dug around in the Presonus Inspire forums for help? I've been over there with the FireStudio I use here. Make sure you've downloaded the latest updates for the Inspire, too.
Cheers,
