[Bug 59078] VIA 8235 embedded card not working: freezing desktop in Dapper

[Myrgen]

Public bug reported:

I am new to Linux, and installed Ubuntu 5. I was very happy with it, no problems at all. Then I upgraded to Dapper Drake 6.06, and problems started popping up.
1) Video started 'hiccuping'
2) Audio was hiccuping too
3) Mouse pointer is sluggish, making it a nightmare to do anything
4) Eventhough the system recognizes a blank disk inserted, when trying to burn it, it asks me to insert a new blank disk, eventhough I tried even with a very little file.

After doing a full reinstall, I added updates and apps one by one, changing some settings, one by one, rebooting each time. I finally found out that the source of the problem was the sound card:
The system set the 'camera' as the default sound card, (Logitech webcam), shows only the microphone properties in the toolbar, and when I changed it to the VIA 82XX sound card I have, then rebooted, the sluggishness of the mouse came back.
I reset the default to 'camera', rebooted, and everything was fine again.
Everything except that I have no sound, hence no video either

mesg | grep snd doesn't give any output at all.

output of aplay -l:

Followed the advices received, but no joy. 
System unmanageable as soon as I attempt to open an audio or video file.
I asked on IRC, and was told to post here.
I reinstalled Breezy to be able to work, waiting for a possible solution.
Thank you.
