I tried
# rmmod snd_hda_intel
# modprobe snd_hda_intel model=macbook
which seems likely to be the right one since I have the newest model of 
Macbook (mid 2007).  That didn't help.  I also tried with 
model=targa-dig in case anything happened with that (nothing happened). 
lspci gives

00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High 
Definition Audio Controller (rev 02)

which I couldn't match up with anything in that documentation (

aunpack
alsa-driver-1.0.14/alsa-kernel/Documentation/ALSA-Configuration.txt
)
