Ubuntu :: No GStreamer Plugins Installed After Bad Shutdown

I was having trouble getting my 8.10 box to restart... it appeared hung on a line talking about alsa (I don't recall what it said). I started back up and the volume icon indicated it was muted. I unmuted and, lo and behold, I have no sound. So, I tried to follow the alsa upgrade instructions at [URL].

When I tried to run the second script:
Code:
sudo sh ./alsa_2.sh

I got this:
cp: target `/lib/modules/2.6.2*/ubuntu/media/snd-hda-intel/snd-hda-intel.ko' is not a directory
cp: cannot stat `/usr/src/alsa/alsa-driver*/modules/*': No such file or directory
cp: omitting directory `/lib/modules/2.6.24-16-generic/kernel/sound/'
cp: omitting directory `/lib/modules/2.6.27-14-generic/kernel/sound/'
cp: omitting directory `/lib/modules/2.6.27-15-generic/kernel/sound/'

And now my volume indicates it's muted again, and if I try to adjust it I get this error:
The volume control did not find any elements and/or devices to control. This means either that you don't have the right GStreamer plugins installed, or that you don't have a sound card configured. You can remove the volume control from the panel by right-clicking the speaker icon on the panel and selecting "Remove From Panel" from the menu.
