My 60-persisten-storage.rules creates device nodes. It does not mount
anything. Is your's different?

So my devices nodes for harddisks exist, when alsa restores it's levels. Does
not solve anything.

We are speculating?
*You* were wrong about the assumtion that /var/lib contains databases.
*You* were wrong about the assumtion how action "add" works.
And *you* are wrong about the assumption, what 60-persistent-storage.rules
does.
Yet you claim, that *I* don't know my system.
I'd say, do your homework, then we can talk.
