I found a potential bug for i915 regarding to ELD parsing.
I was trying to monitor ELD by watching "/proc/asound/card0/eld#3.0" and I realized that the ELD might failed to read from HDMI when AC power is not plugged.
This looks like a potential hardware or driver issue, does anyone aware of this?
I am also looking for the right place to file the bug, please suggest.
