Here it comes. I used lspci -v, but if you know your numbers:

Some things I do not understand:
"If your hardware is not activated automatically..." it is activated
automatically because its driver gets loaded at boot time using an entry
in /etc/modules. There is no manual
action involved. I think you mean "If some piece of code (udev) does not
recognize your card at some time (when udev runs) in the boot process".
Then there is the fact that it did work before the upgrade, it is an old
card so why would there be a change in the {sub,}system & {sub,}vendor
ids?
What is the point of having these ID's when they change overnight for
older cards?
--O yeah, we changed the ids, so from now on some (version) of the card
has the old id, and some (newer) version (but the same card of course)
can be recognized using the new id.
Then someone thinks: well, lets change the recognition process by
assuming every card has the newer id, so everyone with a card
bought before date X must buy a new card. This makes no sense.
I have a kernel Oops in my dmesg, maybe this destroys the proper
recognision?
But here the module is already loaded (because of the entry
in /etc/modules? when I remove that line I get the same Oops
but without the snd_... modules)

[4294695.976000] <6>Real Time Clock Driver v1.12
Maybe here the module tries to load but fails for some reason (because
it is done by udev), while later (when it is done by
S15module-init-tools) it succeeds.
Or maybe it fails because it is already loaded, or...? It probably has
nothing to do with the sound config since at this point the driver is
already
loaded.
My thoughts: this udev thingy is not doing its job. You say well the
udev system should also handle dynamic modules, but as I already
showed,
then the sound does not get restored. So even though a dynamic driver is
loaded which should trigger the udev init action, and at that point
the card is recognized and operational, udev does not restore its
settings. So udev only restores when it ADD's the module itself, not
when done later
by another process.
How can it be that some parts of the OS do know that the sound card is
present and operational (I hear sound after unmuting) while other parts
(this udev part) is ignorant (since it is not restoring the settings by
itself).
I looked in
/usr/share/misc/pci.ids
for my card id.

The kernel driver snd-emu10k1 can look in /usr/share/misc/pci.ids to get
the id?
Correct, correct...it works for me. The "correct" way does not work for
me. Probably
some other changed component after the upgrade is not totally correct
either.
