Making Soundcard Work in Macbook Pro

After installing Debian 5.0 (Lenny) on Macbook Pro (4,1), I found that
sound card was detected, but there was no sound. Then, I come to know
that, model=mbp3 option must be passed to snd-hda-intel kernel driver, to
make soundcard work. This is content of /etc/modprobe.d/sound file.

$ cat /etc/modprobe.d/sound

options snd slots=snd-hda-intel
# u1Nb.bVcdGDjFCiF:82801H (ICH8 Family) HD Audio Controller
alias snd-card-0 snd-hda-intel
# Add the following line as an option to snd_hda_intel module
options snd_hda_intel model=mbp3
