AppleHDA HDMI Audio [Guide]

HDMI audio working
User error, see Post #1/I. Before You Install HDMI Audio/3 and 4

Oh believe me I knew that! My other Hackintosh uses sound via DP so I know the volume controls are on monitor/TV not on the computer.

Anyway, I got it working, sort of. Discovered it purely by an accident. Here the deal: after each reboot there is no sound. If I go to TV controls and select expect sound setting and switch there HDMI Audio format from Bitstream to PCM or vice versa the screen goes completely black for a sec or two and the suddenly the audio starts working. The audio then works until next reboot (I can log off and log on and things are fine).
Do you know what might be the issue? Anything fixable by changing few settings? I'm not seeing this behaviour with any other HDMI devices plugged in (such as FireTV).

Thanks for all your help! I'm already quite happy how things are given that I can get it working with a little inconvenience after each reboot.

No experience connecting directly to TV. macOS does not support LPCM, what app?

Understood. I will try again. But, will disabling the other patch (HDAS to HDEF), disable the onboard sound?

Thanks.

Hello,
i have Sierra last update on Q170T MB + Core i5 6500T(Intel HD 530), no external GPU and working machine (fresh install Graphics is ok, NET is ok) except audio - no device at all.

I just instaled MacOS by Unibeast and later i have used Multibeast to fix Ethernet and Graphics.. I didnt do anything special with Clover and ssdt etc..

I want to use HDMI audio and connect HP LP2475W+its audio out monitor as audio device with HDMI switch between, its
working fine with Windows and consoles.

I have tried your script above (130_v.0.6), but i have got message:
no IOreg/ HDEF, Bios/audio/disablet or ACPI problem.

I have installed Multibeast 100 audio first, regarding of guide, i should rename HDA, in config.plist is this lines:
<key>FixHDA_8000</key> // This should be renamed?

Should i disable Realtek HD (887) audio in bios or not (i though it would be better keep it enable because of some MICs in future, BTW are USB audio cards and mics working)?

What is framebuffer edit required for Intel HD 530? Does it mean any action on my side?

What i should do next?

Hi Toleda

Launched audio_cloverHDMI-130_v0.6.command, without problems, but HDMI is not present in output options.
