This makes HDMI audio work on Linux 3.2.x (0 <= x < 6).
My initial report of this issue can be found at https:/
I used to use a custom patch, baked for me by danvet, to make things work from 3.2.0 to 3.2.5. After switching to 3.3.0, I had to make use of another one, effectively pasting my old, working version over the current incarnation of intel_hdmi.c. I'll attached both patches to this bug for sake of completeness.
