At first I thought I had the same problem, but now I am wondering if I do. I have no sound, same 82801I controller. I noticed in Sound Preferences, in the Hardware tab, I don't have any devices listed and pulse audio is constantly crashing (Bug #421505).
I updated from Jaunty tonight (around 11pm GMT) and sound disappeared.
Also in Sound Preferences I noticed that the out put device is "Null Output" (screenshot attached)
