Put this in your alsa conf file in /etc/modprobe.d/ :

options snd slots=snd_ice1712,snd_hda_intel
options snd_ice1712 index=0
options snd_hda_intel index=1

This is from my system, obviously replace snd_hda_intel with the driver 
name of your webcam. You could also blacklist the webcam snd driver. 
Check with aplay -l
