Hi Antonio! Some of these new "High Definition Audio" cards can be very tricky to make work. At first, my "nVidia Corporation MCP51 High Definition Audio" which is actually a "Conexant 5047", worked without a hitch, both in kubuntu 8.04 and debian testing (it was "testing" back in january of this year). After a kernel update from 2.6.22 to 2.6.24, it just stopped working. I spent two days to find out that i had to append "options snd-hda-intel probe_mask=1 model=laptop" to '/etc/modprobe.d/alsa-base'. I did it, rebooted, and it worked!! Find your card here: /usr/share/doc/alsa-base/driver/ALSA-Configuration.txt.gz , try the options shown there and see if your card works.
