OK in the BIOS for the IONITX, all revs.
In Chipset > Southbridge Configuration there is an item for AZALIA AUDIO.
The options are Disabled, Internal codec + External codec, Internal codec, and External codec
Default option is Internal codec + External codec.
According to the BIOS info, 'Internal codec' is NVIDIA HDMI audio controller, while 'External codec' is ALC885
According to Phill, HDMI does not work in Internal only mode and he had to select Internal + External, further testing is needed.
Kernel modules that need to be compiled or build in are as follows
To enabled HDA
CONFIG_SND_HDA_INTEL=y
For mini-jacks and spdif
CONFIG_SND_HDA_CODEC_REALTEK=y
For HDMI
CONFIG_SND_HDA_CODEC_NVHDMI=y
Not sure, Phill had it on, I didn’t question it.
CONFIG_SND_HDA_GENERIC=y
aplay –l from a working system with both HDMI and spdif audio.

Unfortunately whether you build one or both modules it lspci only tells you HDA Intel

If I recall correctly item 19 was missing before I activated the realtek driver.
Anything else you want to know?
