It might be worth asking on the alsa-user list. A while back with someone 
having problems with a sound card problem on a laptop, I suggested a USB one, 
but the reply was that USB ones need a bit of extra work to get them going. 
Either look on the archives or post to the list. I think the reply to get 
them working was something to do with dmix.

and to post to the list, but you have to register

Hope you get it fixed.
