I have the same problem with 2.6.22-11 on a D830. Under the latest version of 2.6.22-10 I could get everything to work if in installed the kernel version of the snd-hda-intel module instead of the one from the linux-ubuntu-module package. However, in 2.6.22-11 the kernel version does not exist and so I can not get any sound to work in 2.6.22-11.
