There are hundreds of laptops and motherboards out there and every one of them seems to need its own particular option added to the /etc/modprobe.d/alsa-base.conf file to operate properly.

See this link:

To use the database, find the make and model of your machine and then open the alsa-base.conf file as root so you can edit it

sudo gedit /etc/modprobe.d/alsa-base.conf

post #22 of that thread is a user with a Dell Vostro. Adding the following to the end of his alsa-base.conf file worked for him.

options snd-hda-intel model=dell

Also look for someone who might have the same card on a different laptop.

Hope this helps

Can you reproduce this symptom in a daily-live build of Karmic, preferably today's (20091008) or later?
