Well that's really strange.
Post your IOREG after the new config file change. and with the HDMI screen connected to the HDMI port.
You are sure the cable & screen can produce audio when connected ?
BTW, you do not need IGPU to enable HDMI audio.
PS. Thinking about it, your IOREG showed that HDMI audio driver was working BEFORE you enabled AddHDMI. Something is enabling it so you need to investigate what you have added. May be your USB audio ?
Here is the new file, this time I deactived IGPU. The HDMI screen always was connected to the HDMI port since it is the only one that I use.
Yes I'm sure the cable and screen can produce audio because I tested it time ago with a different GPU, in that opportunitie I was able to select "DELL2440" from audio output choices.
I'm definitely sure that nothing new have been added, USB headset always are connected.
