+++ This bug was initially created as a clone of Bug #61981 +++

I think I sent my original bug report to the wrong queue.

Simply this system has been configured to use HDMI audio and on this kernel
there is no output.
I did try on 3.12-rc1 but I had problems booting the system which have been
fixed with 3.12-rc2.
The system works on 3.11.1 with a hand crafted patch of the early HDMI audio
work intended for 3.12 so I know the basic setup works. 

Since the original bug report I have been attempting to bisect the problem to
identify the commit that caused my system to stop working on the 3.12 rc's.
Here is my bisect log as you can see the only good commit for me is Alex's
please advise:
