alsasound is a udev wrapper for alsa. As udev is starting before alsasound, it
can append sometime that the module order will be wrong.
Restarting /etc/init.d/alsasound will give you the wanted order.

One typical case is with usb sound cards. They will be loaded beginning with
sound card 0 by udev, and alsasound will load the other sound cards after the
usb ones.

To prevent this, the simplest way is to blacklist the ALSA module loaded by udev
into /etc/modprobe.d/blacklist.conf. They will be loaded only by alsasound and
in the defined order.
