Greetings,
Pulseaudio can no longer detect sound cards on kernel 2.6.34-rc1.
Note that 2.6.33 is OK.
I noticed that the related sysfs directories/files changed.
Note that the card0/ directory is gone in new kernel:

I don't see this problem on 2.6.34-rc3.
Did you change CONFIG_SYSFS_DEPRECATED* kconfig between 2.6.33 and 34?
