Hi,
I have the same problem and I was reading this thread and in my case I did this and the information is after the quote:

Originally Posted by the.drizzle OK, there's your problem; you're not loading up the new 2.6.31 kernel, hence the alsa modules not loading either. You need to edit your menu.lst file to load the correct kernel, and I have a hunch you've got the new (correct) file sitting somewhere where grub is not seeing it. So that I can give you step-by-step instructions, I need to know a few things. First, what is the output of $ls /boot and also, it would be handy to know your partition table. Please paste the output of $sudo sfdisk -l /dev/sda (or whatever the label of your hard drive is, i.e., sda, sdb, etc...) This will allow you to see where the actual boot device is; it's then your job to copy the 2.6.31 kernel onto that sector, as well as the new menu.lst file. EDIT: Actually, since it will speed this up, can you also post the output of $cat /etc/fstab

Ubuntu 9.10 comes with a new kernel.
What you are experiencing is typical for a kernel upgrade.
Since you UPGRADED from 9.04 to 9.10, you have a new kernel, but still the old ALSA drivers (whoever forgot to make them part of the upgrade)...

You need to recompile the ALSA drivers.
Or you can edit grub (the bootloader) to load the old kernel with the new OS.
/boot/grub/menu.lst (grub1) OR /boot/grub/grub.cfg (grub2)

Needless to say you then will experience problems with the old kernel and the new drivers of the upgrade...
