udev take its options from udev configuration files placed in /etc/udev/*. Andnot from modprobe.conf or whatever file is associated with modprobe. They justdon't are the same programs and don't use the same configuration files. (manudev, man modprobe.conf)
And again, if udev load at boot time some sound module, it will be the firstsound card regardless of what is in modprobe.conf. When alsasound is startedlater in the boot procees and found a sound module allready loaded by udev, itwill ignore it and do what it can to load the remaining drivers. If the allreadyloaded driver is not the first sound card in modprobe.conf, the final order ofthe sound card will be wrong according to modprobe.conf.
