--- Comment #9 from Ilia Mirkin <imirkin at alum.mit.edu> ---
There shouldn't be anything in the DDX that affects HDMI audio (or, indeed,
HDMI). All modesetting is done by the kernel ("KMS"), and that includes setting
up all the proper audio stuff.

So... two questions that I don't feel were fully answered:

(a) Does HDMI video work fine with nouveau in the kernels that you've tried?

(b) Can you test out a 3.7-based kernel (3.7.x should all be fine for this
exercise, the "refactor" patches are generally not backported into the stable
series) and see if HDMI audio works there?

And a fresh question:

(c) Can you try unplugging and then re-plugging the HDMI cable after the
computer is all booted up and check the ELD status then? There's an old bug
that alludes to a timing issue between nvidia and alsa loading, and I have no
idea if it's fixed (bug #32406).
