Check connector-type under framebuffer@1 to be certain it is <00 08 00 00> (HDMI).

Yes it is 00080000. Before connecting the HDMI cable it was that, after it change to 00040000 (I told you about that in another post and you told me it was normal behavior). I still gonna attach the ioreg before using the HDMI cable and with the TV connected to it

Try without FakePCIID_Intel_HDMI_Audio.kext.

Try without FakePCIID_Intel_HDMI_Audio.kext.

I try that and it works. I now have audio using the HDMI, the only problem is, the volume bar to adjust the volume does not work (appear gray). And the monitor that i use dont have a volume control built in so i relay on my computer to adjust that.

It is as per Apple design.

You're not injecting a layout-id.
You have it disabled as #layout-id in config.plist/Devices/Properties.
