alsaconf searches for sound cards and says: ‘No suported PnP or PCI card
found. Would you like to probe legacy ISA sound cards/chips?’.

lsmod | grep snd output is:

According to Corrado, the MacBook uses the same sound card that my netbook
uses. This wiki page says the model parameter can be either mbp3 or mb5:
http://wiki.archlinux.org/index.php/MacBook_Aluminum#Sound

I've configured it as mb5 and nothing changed. I'll configure as mbp3 and
post if something improves, but I doubt that since the wiki page does not
say anything about differences between them.
