To add to this: I remembered that I use the linux-backports-modules-alsa-lucid-generic package. This package has installed version 2.6.32-27; and when attempting an upgrade I get the error message that the backports- modules-alsa-2.6.32-28-generic package is not present, and thus not installable.
So, for now I assume that the error is due to this backports-modules package not (yet) being updated. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/708586 Title: Kernel update to 2.6.32-28: no sound through speakers, headphone working -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
