Those are usually for smartphones and other System-On-Chip embedded
system. How about:

# grep CONFIG_SND_HDA_CODEC .config

It is possible that the headset runs off a different chip and
you're missing the codec driver for it. To check enable them all in
the same way you're building your other audio drivers (modules or
builtin). If it works you just need to figure out which one you
need and disable the rest.
