No Sound on Fedora 11 2.6.30 kernel (2.6.29 works fine)

[gaf-mNDKBlG2WHs at public.gmane.org (Jerry Feldman)]

When 2.6.30 first hit my system, I got a bit of static, but not the pops
others reported, but it is now quiet. Rebooting to 2.6.29, sound works
fine. lsmod shows the same modules were loaded in .30 and .29. I might
try to recompile the Alsa driver.=20

alsa-info.sh information looks ok.
