Both look OK.
Please show your kernel config and /proc/asound/card0/codec#* contents. Did you choose CONFIG_SND_HDA_CODEC_* properly?
Also, please be more specific about your hardware. The implementation of HD-audio stuff is deifferent greatly among products. It's very important to know what kind of machine (h/w vendor, product name, model, etc) to identify whether the configuration is known or not (i.e. it was really supported or it worked just casually).
