ubuntu9.10, alsa .21, NO sound (not even upon starting)

we already had 9.04, but after upgrading to 9.10 there were endless problems, so i reinstalled 9.04 -with more problems reappearing[[could not even mount usb-sticks]]- and then upgraded to 9.10. Most(all) problems solved EXCEPT SOUND. There is NO sound; not even at the beginning, even though everything seems to be working fine (time running and stuff..).

After endless googling, checking the System>Preferences>Sound etc, i am sure (...) that i cannot deal with the problem alone.
I have been using ubuntu for a year now, so i am an absolute beginner.
I have seen 2 extra sound cards apart from the motherboard one.

I followed this (https://help.ubuntu.com/community/SoundTroubleshootingProcedure) link and successfully upgraded alsa to 1.0.21 following this (http://monespaceperso.org/blog-en/2009/08/31/upgrade-alsa-1-0-21-on-ubuntu-jaunty-9-04/) link.

Here are some outputs:
