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).

What's the output of
aplay -l 
1:05 p.m.
And
:~$ cat /proc/asound/cards
?

Kerl,
My desktop (AMD Threadripper based) has an HDA interface, but no mixer.
Instead for sound output it uses a built-in USB based sound card, which
up-until last year the kernel did not recognise
(https://bugzilla.kernel.org/show_bug.cgi?id=210783). Does your
motherboard have a similar setup?

No, its pci-connected.

Ok, found the culprit, the kernel was configured
with dynamic minors which doesn't play well with
static /dev. This config kicked in due to a hdmi
setting, so I missed it.
$ grep DYNAMIC_MINOR config-4.19.182-rt74a
# CONFIG_DVB_DYNAMIC_MINORS is not set
CONFIG_SND_DYNAMIC_MINORS=y
# CONFIG_USB_DYNAMIC_MINORS is not set
$
Thanks, for all help.

This card is listed as obsolete, and at a quick look I can't see it as being
supported by ALSA.

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.
