OMG I found a culprit in /etc/modules-load.d/
-rw-r--r-- 1 root root 14 Jan 24  2018 yast.conf
cat /etc/modules-load.d/yast.conf
snd-hda-intel

Bingo! Removing this one just kill the problem, no more snd module in initrd

You already know that, but you're an ace!!!

I'm just closing now this report. Many��������������� Thanks
