You have Ubuntu 10.04.1. Did you upgrade Alsa yourself to 1.0.23? Just checking, because you have Alsa driver 1.0.23 but Alsa Lib 1.0.22. Not sure what are the defaults in 10.4.1.
The last part of the alsa-info output says
[ 31.392115] ALSA ac97_codec.c:2082: AC'97 1 does not respond - RESET
[ 31.408122] ALSA ac97_codec.c:2091: AC'97 1 access is not valid [0xffffffff], removing mixer.
[ 31.408142] ALSA ali5451.c:1868: ali mixer 1 creating error.
In addition, the earlier messages show that several parts of the soundcard have not been detected properly.
Your chipset is ALI5451.
Your first option would be to follow the discussion at http://ubuntuforums.org/showthread.php?t=1043568 and try to manually detect the soundcard variant, specifying possible options.
It's possible that if you specify the correct 'model', the card will get properly detected.
To test if you get sound (try this now!), use the command
aplay -D default /usr/share/sounds/alsa/Rear_Left.wav
This command bypasses PulseAudio so it should show if Alsa works; if it does not work, set a different 'model' from above and try again.

in case you can add any options.
Are you still getting those errors:
What's going on in alsamixer/gnome-alsamixer:Code:dmesg | grep -C1 -E 'ALSA|HDA|HDMI|sound|hda.codec|hda.intel'

Try disabling 'External Amplifier' in gnome-alsamixer. You may want to toggle some of the other options there as well.
Alsa 1.0.23 was released in April 2010. Could you give a try for Alsa snapshot (very latest) from http://www.alsa-project.org/main/index.php/Download Note the link to snapshot.
Finally, produce a fresh alsa-info.sh with this snapshot enabled. We want to see whether the kernel messages are gone.
