I just upgraded to 8.04 from 7.10 and my sound stopped working.After extensive googling and desperate attempts it seems like i have found the problem, but not found a way how to solve it.
Seems like the drivers are missing from
(it only lists ac97_bus.ko and soundcore.ko)
and if i boot to an earlier kernel, 2.6.22-14-generic, via grub the sound works fine. The /kernel/sound/ directory for that kernel version lists loads of things.
Any suggestions on how to get these drivers installed for my latest kernel? apt-get install linux-ubuntu-modules-2.6.24-19-generic will just say that its installed already.
ps. Using Dell XPS M1330 laptop if that matters.
