That's my guess as well. I think the hardware may still be doing some
form of data negotiation with the HDMI display device at that

Hi Christopher,
Now, onto the intel-gpu-tools test. I ran intel_audio_dump as requested
and it only comes back with Couldn't map MMIO region: No such file or
directory. I spent 10 minutes looking around on Google to no avail. It
seems it tries to mmap() something that doesn't exist.

Christopher,
The dump tool did not work with that environment variable either.
However, it occurred to me that intel_audio_dump may be too outdated in
my distro. It was built on 2010-04-01, v1.0.2+git20100324. If I look at

Hi Christopher,
I don't find anything wrong with the ELD parsing code, however I do
find a bug that prevented ELD from being passed to the audio driver on
SandyBridge.
I just posted the fix. For your convenience, it's attached in this
email too.
Thanks,
