Comment 32 for bug 462098

I should have been more precise in my description in message #29. What I meant by the parenthetical remark was that I had no sound (and still do not) after each of the following steps in order:

* Installed Karmic 64-bit to an empty formatted partition (ext4).
* Enabled the karmic-backports repository (System->Administration->Software Sources->Updates (tab)->Unsupported updates (checkbox)) and updated all packages (System->Administration->Update Manager->Install Updates).
* Installed linux-backports-modules-alsa-karmic from synaptic.
* Followed the exact procedure listed in #25 above, with the exceptions of (a) fixing the typo mentioned in #28 and (b) using nautilus to uncompress the archive since the tar command listed gave an error.
* Reinstalled linux-backports-modules-alsa-karmic again just now.

After each of these * starred items I rebooted, and tried to play a .wav file in Totem after checking the volume level and mute status in the System->Preferences->Sound Preferences application. None of them resulted in any sound, even jack noises.
