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.
Good luck!!
