[linux-audio-user] maudio audiophile 24/96

I'm trying to convert my collection of cassette tapes over to CDs. I purchased two nice used tape decks off ebay. The nicer of the two is connected to my computer, which is a recent model athlon64 3000+ w/ 1G RAM. Sound was very rough captured with 'arecord' through the computer's built in sound chip so I bought a maudio audiophile 24/96 from newegg to get a clean dac. But my common Linux mixers don't know what to do with the maudio and I feel I may have purchased a fancier audio card than I know what to do with (most mixers certainly don't know what to do with it). kmix does a reasonable job of picking up and labeling the inputs/outputs/controls. But I don't know how to use them. I'd appreciate being pointed to: email list forum/irc doc url that might help me out. THANKS
