I'm having the same problem on a desktop with a Realtek ALC850 (Board Asus K8N-E Deluxe). The modules 2.6.20 work fine, the 2.6.22-14 and the backport don't. I can actually boot with 2.6.20, make a soft reset, reboot with 2.6.22-14 and everything seems ok, but when cold-starting with 2.6.22-14 there is no sound and in fact I get:

"ALSA lib pcm_dmix.c:864:(snd_pcm_dmix_open) unable to open slave"

which is also reported here https://bugs.launchpad.net/bugs/150129

I'm not really familiar with the sound drivers (just used to work ;-)) and I tried most of the suggestions I found (recompile, use backports, set options) already. Any further idea on what could be broken?
