I'm trying to get HDMI audio working on a ALC1200 integrated audio card on an Asus P5Q-EM motherboard (Intel G45 chipset).
I notice there is a lot of ongoing work on this chipset at the moment, but from what I gather, it should work. Because of this, I made sure to try the latest code, both 1.0.18 and 1.0.18a.
I am eager to get this going and I'll be happy to provide any additonal information necessary. I've found and run one data-gathering script, the results of which are here:

Here's results of the same tsalsa script with alsa 1.0.18:

The major differences between them:
