AppleHDA HDMI Audio [Guide]

[vahids]

I just restart my computer and HDMI missed from output devices list!

audio controller

Chip in the TV for HDMI audio, volume control is one of the chip's functions.

I tested on TOSHIBA TV too, Volume controller disabled in both

HDMI audio is a digital signal, no volume control at the source; by design.
Toshiba/Samsung convert digital signal into sound, volume is controlled at the device making the sound;
use the Toshiba/Samsung remotes.
Search for 3rd party solutions if the TV remote is unacceptable for volume control.
Off topic.

HDMI device (SAMSUNG / TOSHIBA) missed after rebooting.

$ioreg -rxn IOHDACodecDevice | grep VendorID
      "IOHDACodecVendorID" = 0x10de0072
  |   "IOHDACodecVendorID" = 0x10ec0900

Finally Fixed:

I tested a lot and I didn't find reason of the random missing HDMI devices in output devices list, So I think the following changes fixed my issue. I wish it help others with same issue:

I restored original AppleHDA.kext in S/L/E and moved Lilu and WhatEverGreen kexts to /L/E
and:

$ sudo chmod -R 755 /Library/Extensions
$ sudo chown -R root:wheel /Library/Extensions
$ sudo touch /System/Library/Extensions && sudo kextcache -u /

I attached Original AppleHDA.kext of macOS 10.13.6 (17G65)

I have the same issue as @vahids . The HDA device randomly appears and disappears everytime I switch on my computer. When it appears, I can happily listen to audio - working flawlessly.
I have whatevergreen.kext and lilu.kext installed in EFI/CLOVER/kexts/Other. Does it make any difference compared to /L/E?

Thanks for helping. I wasn't really reporting a problem, but more like asking a question
Could you please just tell me whether it makes any difference if I install whatevergreen.kext and lilu.kext in /L/E compared to /E/C/O?
