Those options are found when you first configure your sound card, choose 'Advanced setup with possibility to change options' after hitting 'edit'.

here's the /etc/modprobe.d/sound:

--------------------------------------

options snd-hda-intel enable=1 index=0 model=ref position_fix=1
# u1Nb.38og6MBANWF:82801G (ICH7 Family) High Definition Audio Controller
alias snd-card-0 snd-hda-intel

-----------------------------

Hope this helps!
