I've downloaded the latest alsa 1.09rc4a and tried it with no success. 
Is there anything I can do
to further troubleshoot this. I configured the sw --with-debug=full but 
didn't see any additional output.
I am willing to get my hands dirty if someone will give me some 
direction. This laptop is used by my teenage daughter and she has to 
have sound ;).
