I have tried to patch 3.11.7 and the code in patch_hdmi.c looks too
different to be able to able to manually merge the rejected hunks.

What is sound-next? A git branch? Where can I get it?

How independant is the sound subsystem from the rest of the kernel? My
guess is that it is not that tightly coupled with the rest and dropping
sound-next version of patch_hdmi.c into my 3.11.7 source tree could work
or require minimal work. Will upgrade to 3.12 in a couple of day....
