Attach ioreg without the HDMI device plugged in.
You should also test without FakePCIID_Intel_HDMI_Audio.kext. Not all hardware requires it.
YOU ARE A LEGEND!
Removing FakePCIID_Intel_HDMI_Audio.kext did the trick!! Not sure why I was convinced it was required. Both sound and picture working perfectly on both laptop and TV. (TV needed an extra EDID override for forced RGB mode in order to get a full resolution without pink/purple tone, but that was an easy fix).
Thanks again RehabMan!
