Bug#660111: [3.0 -> 3.1.8 regression] intel ibexpeak hdmi no sound out

That patch that you mention is included in the 3.0.x kernels as the
matter of fact. Thus I don't think it would have caused the problem.
See for example:

http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=commit;h=384a48d71520ca569a63f1e61e51a538bedb16df

and

http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=shortlog;h=384a48d71520ca569a63f1e61e51a538bedb16df

I didn't find this out the easy way. I compiled the kernel with your
instructions and suddenly the name was 3.0.0-rc2 instead of 3.1.0-rc2
as I expected.

I'll try to find a relevant patch for alsa hda hdmi in the 3.1
development series. I've looked a good candidates, but always on the
"wrong" development cycle...
This one seems promising though:

http://git.alsa-project.org/?p=alsa-kernel.git;a=commit;h=0b6c49b59fb272c1a20f79202693ed1072e9548c

How did you get that number you gave me before to use with git?
basically I'm asking how do I get it for this patch ? I'm going to
simply download the snapshot and try it for now. There are other
suspicious patches submitted around the same time. I shall try them at
some point:

http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=shortlog;h=0b6c49b59fb272c1a20f79202693ed1072e9548c
