I have a lenovo desktop computer which I cannot make sound work
on, what am I missing ?

It's a HDA AD1882 "sound card", but alsamixer says "no card".

alsa-info, kernel config and lenovo doc (see p.80) in:
http://aspodata.se/tmp/sound/

///

I run with static /dev (no udev) and
boot directly to disk (no initrd).
