Ubuntu 9.10 Karmic Koala Upgrade No Sound

After upgrading to Ubuntu 9.10 Karmic Koala my system was without sound. Alsa couldn't find any sound cards.

00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01)

alsamixer: function snd_ctl_open failed for default: No such file or directory

aplay -l
aplay: device_list:223: no soundcards found...

After poking around I discovered that the updater did not update /boot/grub/menu.lst to use the latest installed kernel.

You can fix this automatically by running update-grub. Choose install package maintainer's version if you don't have any custom entries.

Perfect.Thanks for providing such an easy solution. I found several pages that suggested very difficult ways of accomplishing the update, while you showed how to do it with a single command. Thanks
