hi, after upgrading to mojave 10.14.3 hdmi audio is lost, only have headphones jack working using appleALC and fakepciid intel method, but...i noticed that if the computer boots up and the monitor ( LG TV ) is turned off and then after booting i turn the tv on everything goes fine: both audio hdmi and jack are present and work. hdmi hot unplug and plug back gives no result if tv is turned on before computer- only audio thru jack aux...any ideas thanks.

system: Intel NUC6i3syh with HD520 graphics
monitor - LG TV
mac OS: mojave 10.14.3 ( 18D109 )
installed using Rehabman Nuc installation method with appleALC and fakepciid intel hdmi audio.

You have identified the problem correctly, Intel HDMI audio codec is not present if TV is on during boot.
Turning the TV on after boot is a hot pug and macOS recognizes the Intel HDMI audio codec

installed using Rehabman Nuc installation method with appleALC and fakepciid intel hdmi audio

Suggest posting to RehabMan's Mojave NUC6 Installation thread.

Hello! I have a t470P thinkpad i7 7700HQ. Audio is perfectly working with lilu and applealc. Problem is that I can't get minidp audio to work. To say the truth it worked once while spoofing to skylake gpu ids but it lasted one reboot. I don't really know what is going on, and i'll be glad if some one can help me. With fakepciid I don't have any audio at all. Attached debug info, ioreg with and without minidp.

can't get minidp audio to work

The Intel HD630 HDMI audio codec is not enabled, verify BIOS/display audio/enabled.

Hi there,

I'm at a loss right now, trying to get HDMI audio to work again after upgrading my HTPC to High Sierra (Mojave not possible due to HD 3000 graphics).

CPU/GPU: i3-2105 w/ Intel HD 3000 graphics

When I try to run the audio_cloverHDMI script (also older versions), this is the output I get:

HDMI audio codec(s)
Intel:    0x80862805
Integrated Graphics is not installed/enabled
Install AMD/Nvidia HDMI audio (y/n):

I'm pretty sure the iGPU is enabled, at least the GUI feels like it is, and all attempts to enable it "more" resulted in poorer performance.
Or don't the older versions of the script support HD 3000 either?

I attached my config.plist for reference.

Any help is greatly appreciated!

I recently got everything setup and running with my Mojave hackintosh.

I have audio going right now with Bluetooth to my sound bar, however I’d like to have the option to use my HDMI output as well. My card has a display port.

If I used the display port to hdmi would this fix the problem?
