[workaround and cause]

if you delete the file '/var/lib/alsa/asound.state' and reboot, the alsa driver is properly loaded. then, you can tweak the mixer settings to get sound (for me, i have to enable surround sound).

however, the next time you reboot, the sound goes away again and you have to repeat the process.

thus, i believe the problem lies with the alsa startup script. if the file '/var/lib/alsa/asound.state' exists at boot, alsa tries to load it but gets confused and alsa doesn't properly configure. maybe the file isn't properly formatted; i know it refers to controls that don't exist on my card.

$ lspci | grep -i audio
00:14.2 Audio device: ATI Technologies Inc SB450 HDA Audio (rev 01)

the problem is a race condition with the init script. now that init scripts are run in parallel, a kludge was added to /etc/init.d/alsa-utils which simply waits until the file system is available. some other condition must also need to be satisfied. this is confirmed by the fact that the loss of sound for most people first started with Edgy.

Thank you for the comments, but my problem has nothing to do with this kind of bug. I tested your solution but nothing changed.
Here are the required logs for helping you debugging (sorry for answering so late to this bug description ...

I just realized that I forgot the output of cat /etc/asound.conf ~/.asoundrc* for being complete in my previous comment ...

The 18 month support period for Edgy Eft 6.10 has reached it's end of life. As a result, we are closing the linux-source-2.6.17 Edgy Eft kernel task. However, can you confirm if this issue still exists in the Hardy Heron 8.04 LTS release or, alternatively the Intrepid Ibex 8.10 Alpha2 which is also scheduled for release today? It will appear at the following when available: http://www.ubuntu.com/testing/intrepid/alpha2 . It contains the the actively developed 2.6.26 Ubuntu kernel. It would be great if you could test this upcoming release via a LiveCD and verify if the issue still exists. If so, please include the appropriate debugging information as outlined at https://wiki.ubuntu.com/DebuggingSoundProblems and set the status of the bug to 'new' and the bug will be reviewed again. Thanks in advance.

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.
