I usually do installs, it is a way to "clean up" leftover stuff. There
are always small details that you have to fix after an upgrade (in my
experience).

Try the modifications below to see what happens (there's stuff that was
moved from 2.4 without much thought, I think). Remove the lines or
comment them out (prepending a "#"):

Sigh, not much left (or needed)
I see that the fc2 upgrade did not create or modify automatic mixer
state save statements in /etc/modprobe.conf, something like this should
work (add at the end of the file - the following are just _two_ lines):

install snd-ice1712 /sbin/modprobe --ignore-install snd-ice1712 &&
/usr/sbin/alsactl restore >/dev/null 2>&1 || :
remove snd-ice-1712 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; };
/sbin/modprobe -r --ignore-remove snd-ice1712

Do a "/sbin/depmod -a" and restart alsa...
