Post #1/I. and II.

Sir, my equipment is MACOS 10.14.6/Motherboard Gigabyte BKi7HA-7500/BIOS F12/CPU Intel i7-7500u/Intel HD 620

Following this article, It sounds perfectly, but I cannot control the volume at all, including volume up/down and mute,and the HDMI output will be disabled whenever I reboot, replug the HDMI is the solution.

And the framebuffer was patched perfectly by check the system information (32MB becomes 2048MB).

All I do was using the kextbeast to install whatevergreen.kext and lilu.kext. btw, I finally found it out that WEG means whatevergreen.

Then using the clover configurator to edit the efi/efi/clover/config.plist/device/properties, to inject pciroot(0x0)/pci(0x2,0x0) with aapl,ig-platform-id, framefuffer, unifiedmem, etc.

And inject kext to patch to whatevergreen find 03060800 00040000 11000000 replace 03061200 00080000 06000000.

After reading once and once again, I can't figure out the solution. I really need a suggestion.

Thank you for your help.

After last Mojave update, no HDMI audio on GTX650, here is my config.plist and some sceenshots of my system.

Updated kexts (Lilu, WEG, AppleALC)with clover configurator before updating OSX and all works fine except HDMI on NVidia GTX650

Mobo: Gigabyte Z87X-UD3H+i7 4770+NVidia GTX 650 2 GB.

I try to get HDMI following this thread, and no solved.
I don't know what I do wrong.
Please help.

cannot control the volume at all

Missed Post #1/
I. Before You Install HDMI Audio

5. OS X does not provide HDMI audio controls (No volume, no mute, no balance, etc.)
6. The connected HDMI device (TV, receiver, etc.) provides any and all audio controls

Hello @toleda,

I have a Dell Optiplex 9020 PC running latest Mojave with the latest WEG and AppleALC. I'm using the iGPU Intel HD4600. It's connected DP to DP with my monitor LG 27UK850-w

However I'm not getting Audio through DP. I do get Line-out and Headphone port and they work perfectly tho.

I just wanted to quickly ask, do you think this could work for DP Audio?

Thanks a lot

EDIT: changed to another DP port and now I'm getting DP Audio control!! >_<

spent a lot of time debugging on this issue: https://www.tonymacx86.com/threads/...audio-controller-but-not-sound-output.284750/ installed AppleALC first, disabled all past DSDT fixes / patches. Reinstalled whatevergreen, lilu and onboard audio driver kexts with kextBeast (seems copying wont work). Replaced AppleHDA with native one

=> onboard audio works but not hdmi audio

Last Resort, uncheck resetHDA in devices/audio.

=> hdmi audio worked!

Hi
I am updating my old HTPC with HD3000 to HS and Mojave and need to configure again Audio on HDMI.

Post #1 says it's for HD4000 and newer : knowing I will use clover and recent OSX release, should I follow this guide while I have an HD3000 or the previous guide ?

Thanks
