That's correct for snd-emu10k1. You will need to add an alias, and an options
line in /etc/modprobe.conf if your having problems with snd-usb-audio being
set as card0. Check this.
cat /proc/asound/cards
You will probably see snd-usb-audio (webcam) set as card0, and snd-emu10k1
(your actual soundcard) set as card1.
Add the following lines to /etc/modprobe.conf while su'ed to root and with a
text editor (gedit, kwrite or whichever you prefer).
alias snd-card-1 snd-usb-audio
options snd-card-1 index=1
options snd-usb-audio index=1
Save the changes, and exit the test editor, and the shell.
Reboot, and see it if the cards are loaded in the correct order now,
cat /proc/asound/cards
Strange you're having this problem on FC5. I've got a usb-midi-keyboard that I
used to have this problem on earlier versions of FC, but I think since FC3
the problem seemed to be resolved without having to set index options for
snd-usb-audio, and snd-usb-audio is being set as card1 without any entries
for it in /etc/modprobe.conf.
