Well, the situation is that on the machine where I was having the
problem, there was no /etc/udev/rules.dev/udev.rules . Whether udev
didn't put it (e.g. because the postinst script is not idempotent if
interrupted at an arbitrary point), or whether it disappeared through
disc corruption that did not break anything else, I cannot be sure.
I symlinked it to ../udev.rules on that machine, and now udevtest
/class/sound/controlC0 says:
udev_rules_get_name: rule applied, 'controlC0' becomes 'snd/controlC0'
which I understand as "the problem is fixed". I haven't been in
situation to reboot that machine yet to really test it.
What is it that you "just do not believe"? That adding the symlink
solves the problem or that the symlink was not there?

Why does symlinking /etc/udev/rules.dev/udev.rules to ../udev.rules
fix the problem then?
