No, it happens exactly the same even if logged in as root.
I just restarted and tested.

yes

Mine before running alsaconf

 ls -l /dev/snd
total 0
crw-rw---- 1 root audio 116, 4 2009-07-01 07:35 controlC0
crw-rw---- 1 root audio 116, 8 2009-07-01 07:35 controlC1
crw-rw---- 1 root audio 116, 3 2009-07-01 07:35 pcmC0D0c
crw-rw---- 1 root audio 116, 7 2009-07-01 07:35 pcmC1D0c
crw-rw---- 1 root audio 116, 6 2009-07-01 07:35 pcmC1D0p
crw-rw---- 1 root audio 116, 5 2009-07-01 07:35 pcmC1D1c
crw-rw---- 1 root audio 116, 9 2009-07-01 07:35 seq
crw-rw---- 1 root audio 116, 2 2009-07-01 07:35 timer

Mine after running alsaconf
ls -l /dev/snd
total 0
crw-rw---- 1 root audio 116, 6 2009-07-01 11:39 controlC0
crw-rw---- 1 root audio 116, 5 2009-07-01 11:39 pcmC0D0c
crw-rw---- 1 root audio 116, 4 2009-07-01 11:39 pcmC0D0p
crw-rw---- 1 root audio 116, 3 2009-07-01 11:39 pcmC0D1c
crw-rw---- 1 root audio 116, 7 2009-07-01 11:39 seq
crw-rw---- 1 root audio 116, 2 2009-07-01 11:39 timer

There is some differences. Less entries, and notice the time.
I had just restarted the system to cause the problem.
I did each command just a few minutes apart, the first one however shows
a morning time, this is when it does not work, and the second shows the
correct time, after running alsaconf and it is working.
I am not sure what to make of it yet.

no, i have not installed it, mainly such things are default.

Mine,
/lib64/udev/rules.d/40-alsa.rules
# do not edit this file, it will be overwritten on update

SUBSYSTEM=="sound",             GROUP="audio"
KERNEL=="controlC[0-9]*",       NAME="snd/%k"
KERNEL=="hwC[D0-9]*",           NAME="snd/%k"
KERNEL=="pcmC[D0-9cp]*",        NAME="snd/%k"
KERNEL=="midiC[D0-9]*",         NAME="snd/%k"
KERNEL=="timer",                NAME="snd/%k"
KERNEL=="seq",                  NAME="snd/%k"
KERNEL=="mixer0",               SYMLINK+="mixer"

Seems to match yours.
