To be effective we need to know _exactly_ what this recalcitrant card is?

for a start, as root, issue the command:-
# lspci -v

Now select the parts referring to the sound card and post it to the list.
Note that there is a, hopefully remote, possibility that the particular device does not have a Linux driver.

Here are the relevant bits from the 'lspci' command:

The Cirrus Logic controller is the built-in controller on the motherboard. The C-Media Electronics one is the Genius card I got from Lance Blackler.
