I changed kernel back to 2.6.15-23-386 and now sound works again. I just renamed appropriate rows in /boot/grub/menu.lst to load older kernel.
Even touchpad mouse works again. It seems like it's kernel bug but I'm not sure. But it's workaround, not solution. -- Kubuntu 6.06 LTS and KDE 3.5.4 - sound crash! https://launchpad.net/bugs/55898 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
