Sound problems with latest kernel -- formerly a pulseaudio thread but not any more

I've actually tracked it to before that. 

Wine's audio last worked with one of Ubuntu's generic kernels, probably 2.6.28-10. 
Ubuntu's current repository kernel is 2.6.28-11. That's the one I that caused the problem. 
The experimental bug-fix kernel is 2.6.28-12. That does not solve my problem. 
(Here's where I got the kernel: http://kernel.ubuntu.com/~dtchen/test-kernels/ )

When my kernel worked, my drivers were 0.1.19 -- one of Tashaki Iwai's daily stable builds from a couple of weeks ago. 
They are 0.1.19 now, today's daily stable build, compiled against 2.6.29-1-rt8-custom, which is what I am running at the moment. 

My 29-rt kernel is showing the same problems as the two kernels mentioned above. 
FWIW, the person who compiled the RT kernel said that he did so without applying the Ubuntu patches. So that tells me that the change took place outside the Ubuntu patches.
