Ok guys, I found it. I think a lot of people might have the same
problem, because it took me a lot of googling to go through all
different sound-problems people have with different solutions which
sometimes work and sometimes don't work.

In the end I found the following reported bug (sorry I didn't find it
earlier), #82988, see https://answers.launchpad.net/ubuntu/+source/alsa-
driver/+question/82988.

Now in that report is suggested to upgrade alsa, which I found in many,
many, many other reports as well, including
https://help.ubuntu.com/community/SoundTroubleshooting what I guess is
something like "the official Ubuntu soundtrouble guide".

And after the upgrade of alsa finally you have to download hda-verb, and
install it. Now, this works fine, but I was curious, and reinstalled
ubuntu 9.10 again, this time I intentionally did not upgrade alsa and
performed the "hda-dev"-procedure. And guess what, that was all it took.

Sound is working, although I haven't tested it thoroughly yet, since I just got 
it working. Now if I look at 
http://rpmfind.net/linux/RPM/mandriva/2010.0/x86_64/media/contrib/release/hda-verb-0.3-2mdv2010.0.x86_64.html
 a description of the program can be read there, but I copy it here:
"hda-verb is a tiny program that allows you to access the HD-audio
codecs directly, allowing you to send commands (verbs) to them. For
hda-verb to work you must be running a linux kernel with
CONFIG_SND_HDA_HWDEP option enabled."

Now I wonder if I'm using alsa to talk to the sound-card or if this is
directly communicating with the kernel, but hey.... who cares, it works!

Thanks a lot to the people in bug-report #82988 who found out about hda-
dev and especially to Mandriva who made the program. I think it is a
shame, this is needed. Perhaps it can be at least be added to the
SoundTroubleshooting Guide so that more people can find this more
easily.

But for the rest, Ubuntu is great !

Regards,
Hopsa
