snd-hda-intel and Ubuntu 7.04
After upgrading my Toshiba Satellite Pro A100 laptop to Ubuntu 7.04 “Feisty Fawn” my sound card stopped working. The only mixer options available are related to the built in 56k dial up modem.
My A100 uses an ATI SB450 soundcard, which worked out of the box in 6.06, 6.10, and the early beta stages of 7.04. From what I can see, this problem is related to the release kernel not detecting the sound card model correctly.
After searching the Ubuntu forums, and Launchpad, I found this fix posted by Ubuntu forums member “djails“:
sudo rmmod snd-hda-intel
sudo modprobe snd-hda-intel probe_mask=8 model=auto
After running the above commands, your sound card should now work, however, these changes are not permanent, to make the above changes permanent, add the following line to the bottom of /etc/modprobe.d/alsa-base:
options snd-hda-intel probe_mask=8 model=auto
After applying these changes, all components of the Toshiba Satellite Pro A100 appear to be working, including the built in wireless card.
If you need help with your soundcard, or Satellite Pro A100, post below and I will do my best to help out.

ShaH: I don’t have this laptop anymore, but try running alsamixer you should be able to raise the volume of PCM there.
