This message is mostly harmless.  The driver detected the modem codec
in the tree, which isn't supported yet.  In the latest version, this
message is suppressed.  The serious message is "no codecs
initialized".  If this message appears, the driver won't work at all.

If the driver is loaded and doesn't complain like above, the silent
problem is likely the wrong PIN assignment.
For ALC880 codec (you can check it in /proc/asound/card0/codec#*
file), try a different "model" module option.  See
ALSA-Configuration.txt for details.  Make sure that you use the 
latest 1.0.9rc4!

If none of models matches your device, try to build drivers with debug
option and set model=test.  This will enable almost all available
controls for testing.  Check different PIN configurations via
alsamixer, and report it to here together with the content of
/proc/asound/card0/codec#* files.
