It's not the first time that I've seen this problem after upgrading to Hardy 
Heron (8.04) from Gutsy Gibbon (7.10). Another guy has the same problem, but 
with 82801I, rather than 82801H. Same output from the pastebin file, no 
soundcards found, but lsmod shows all modules to be loaded.

Perhaps I'm a bit neurotic about this, but when I installed Fedora 8 (fresh 
install), I had no sounds, but sounds on earlier versions of Fedora had 
always worked (with a bit of editing /etc/modprobe.conf to deal with my usb 
midi keyboard), but Fedora 8 came with Pulseaudio, and it was that, that was 
messing the sounds up. I disabled it by removing the alsa-plugins-pulseaudio 
package, and the sounds came back.

I don't have an instance of Hardy Heron (8.04) installed at the moment, but it 
may be worth looking in synaptic, and if the alsa-plugins-pulseaudio package 
is there, remove it. it will at least remove pulseaudio from possibly 
compounding your sound problems, and when, and if you get the sounds working, 
you can always just re-install the package, if you want pulseaudio that is.
