While there is no package called 'alsa-plugins-pulseaudio' in 8.04 (see http://dpaste.com/53030/ for the default installed pulse packages), I removed it per 'sudo apt-get purge pulseaudio', but it seems not to affect my problem (since the card is not - yet - detected I didn't even start to mess with soundconfiguration / setting up the soundserver).
The problem really seems to be a hardware vs. kernel one and since it
works in earlier kernels it's clearly a regression :( Nailing it down is somewhat harder since there a various different errors with the same
outcome: no sound with this chipset. Those I came across while looking
for a solution: Card is not detected at all, problems loading codec and
module could not be loaded because of unknown symbols. There are also
problems because some modules won't load per default and others where
the sound is working, but with extremely low volume.

I'm not sure what's caused this, but I guess this is the whole part:
[ 41.554112] ACPI: PCI Interrupt 0000:00:1b.0[A] -> GSI 22 (level, low) -> IRQ 21
[ 41.554119] PCI: Unable to reserve mem region #1:4000@febf8000 for device 0000:00:1b.0

[ 41.554131] HDA Intel: probe of 0000:00:1b.0 failed with error -16
You can see my whole dmesg here:

I'm not sure how to check:
$cat /boot/config-2.6.24-16-generic | grep SND
# CONFIG_SND is not set
$cat /boot/config-2.6.24-17-generic | grep SND
# CONFIG_SND is not set
Is that what you mean?

I found a bug on launchpad, that seems to fit to my problem:
https://bugs.launchpad.net/ubuntu/+source/linux-ubuntu-modules-2.6.24/+bug/211644
I will post my error-report there too.
For Dell Laptops there are some suggestions on how to fix this:
http://linux.dell.com/wiki/index.php/Ubuntu_8.04
http://linux.dell.com/wiki/index.php/Ubuntu_8.04/Issues/No_Sound_After_Distribution_Upgrade
A general workaround is also suggested: One could use the -rt kernel, sound should work there. I will test that later (no time right now) and keep you posted.
The posts from Warren Turkal look especially interesting:
