It's a matter of device number assignment. You can achieve it easily
even without udev manually or automatically by some script.
For example, in the new case, minor#5 corresponds to
/dev/snd/pcmC0D2p:
5: [ 0- 2]: digital audio playback
then you need to create a device file like
mknod /dev/snd/pcmC0D2p c 116 5
Write a script to call for each line of /proc/asound/devices and call
it in an init script after loading the sound modules.
