To all of you with a ATI SB450 sound problem in feisty:
If your sound card is an ATI SB450 in a toshiba laptop like mine which used to work in edgy but not in feisty anymore, here is the solution given to me on the alsa-devel ML:
Code:

sudo rmmod snd-hda-intel
sudo modprobe snd-hda-intel probe_mask=8 model=auto

It worked for me. The probe_mask param allows the correct discovery of the sound codec, which otherwise is masked by the modem.
if it does the job for you, make it permanent by adding "options snd-hda-intel probe_mask=8 model=auto" at the end of /etc/modprobe.d/alsa-base
Let me know if it works for you.

For reference:
