Karl:
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).
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.
Regards,
