what's the result of aplay -l ? it will tell you the chipset.
inspect /usr/share/doc/alsa-base/driver/ALSA-Configurations.txt.gz and
see if the chipset is supported there. next you must put
"model=<laptop-model>" in the config file.

edit /etc/modprobe.d/sound:
options <your-sound-module> model=<toshiba>

a friend have same problem before (toshiba laptop) but with ATI IXP 4x0
(chipset ALC861). but finally sound is working again.
hope this would be a clue for you.
