It seems that after upgrading to Karmic you are still booting a non-Karmic kernel. There may have been an issue updating grub during the upgrade.
In a terminal run: sudo mv /boot/grub/menu.lst /boot/grub/menu.lst.backup sudo update-grub sudo reboot After rebooting, in a terminal run: uname -a Verify that the kernel you are now booting is of the 2.6.31 variety. It should look something like: "Linux bradf-home 2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:05:01 UTC 2009 x86_64 GNU/Linux" If, after booting with a Karmic kernel you are still having audio issues, change this bug back to new and run: apport-collect -p alsa-base 473727 ** Changed in: alsa-driver (Ubuntu) Status: New => Incomplete -- No sound in Gnome ans KDE https://bugs.launchpad.net/bugs/473727 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
