What is the name for the sound device?

FWIW, you get unique device name listed in /proc/asound/

A Swissonic device
spinymouse at precise:~$ ls -hAl /proc/asound/ | grep card3
dr-xr-xr-x 2 root root 0 Jun 18 15:14 card3
lrwxrwxrwx 1 root root 5 Jun 18 15:14 U0x170b0x11 -> card3
A Korg device
spinymouse at precise:~$ ls -hAl /proc/asound/ | grep card3
dr-xr-xr-x 2 root root 0 Jun 18 15:14 card3
lrwxrwxrwx 1 root root 5 Jun 18 15:14 nanoKONTROL -> card3

but what names are used for "udevinfo -a -p /sys/block/[...]"?

spinymouse at precise:~$ ls /sys/block/
loop0  loop2  loop4  loop6  ram0  ram10  ram12  ram14  ram2  ram4  ram6
