Different problem.  This is about "select":

config SND_SOC_ALL_CODECS
	tristate "Build all ASoC CODEC drivers"

That enables (sets):
	select SND_SOC_HDAC_HDA
which selects SND_HDA even though CONFIG_PCI is not enabled.

After SND_HDA is selected (above), the Kconfig symbols in
sound/pci/hda/Kconfig are available for enabling, so
SND_HDA_CODEC_CA0132 is enabled but will not build.


One simple solution (but possibly too naive) is:
