I'm experimenting with using ELD information in PulseAudio and found that it didn't work very well with hotplugging. Neither the proc file nor the ELD kcontrol was cleared correctly after unplug, and there was no way (except polling) to find out when ELD has become available.
Did you try Xingchao's patch for drm/i915? It's queued in drm-intel-next:
commit 7b9f35a6dd72f89452c58bbdbaf063027bf857ec Author: Wang Xingchao <xingchao.wang@intel.com> Date: Tue Jan 22 23:25:25 2013 +0800 drm/i915: HDMI/DP - ELD info refresh support for HaswellThanks for the hint. I'm currently developing not on a Haswell machine, but an (I think) Arrandale that I bought a few years ago. So I guess this patch does not have any effect on my hw?
OK, then it's not.
You are testing relatively new kernel, right? For example, the commits for drm/i915 b98b60167279df3acac9422c3c9820d9ebbcf9fb and 3cce574f0190dd149472059fb69267cf83d290f9 are relevant with HDMI audio to make unsol event working at hotplug/unplug. They should be in 3.7.
In anyway, your patches seem individual from the video driver side but the fixes only in the sound driver side, so better to apply.
Will comment on each patch later.
