Well this is a very strange thing, but there should be an explanation
for that. There must be something that alsaconf do in the files and we
do not know. It would be a good exercise trying to discover what the
diferences are. Just curious. For example, take the alsa-conf file that
does not work and rename it as alsa-conf-w3sz. DO the same with sound
renaming it as sound-w3sz. Run alsaconf to make the changes that make
them work. Use the "diff" utility to discover the diferences:

$diff alsa-conf alsa-conf-w3sz > alsa-conf.diff
$diff sound sound-w3sz > sound.diff

and examine the *diff files under a text editor.

It is clear that the sound kernel modules are there ready for use
(/lib/modules/kernel-version). There must be some diferent "alias"
settings. Try to determine wich files are changed by alsaconf.

If you have free time, please send to me every file in /etc/modprobe.d/
