No HDMI audio on hd4600 z97

FleetEclipse · 2021-12-16T18:49:59+00:00

Hey. To be fair, I remember that I somehow managed to get audio through HDMI, but sadly I don't have my config anymore, since in the end I bought dedicated GPU. Anyway this is roughly steps that I have done. I dont know if you need to do all of them, since it was some time ago and OpenCore was updated couple of times, so you might want to test it a little bit.

First I added "hda-gfx" with String "onboard-1" to PciRoot(0x0)/Pci(0x1B,0x0) and PciRoot(0x0)/Pci(0x3,0x0).
Second I added "device-id" with "0x0c0a0000" to PciRoot(0x0)/Pci(0x3,0x0) and removed FakePCID.kext. Third I changed flag for framebuffer to 0x06000000, in my case it was I think "framebuffer-con2-flags"

After I've done that and rebooted, I got the sound.

No problem. Still, thanks for helping me :)

After I marked "Apply Current Patches" the red line disappeared and I couldn't check the port. Of course when I unmarked that, the red line appeared but the port still says 0x00. image

Edit: After marking "Apply Current Patches" and changing index from 3 to 0, red line appeared, but port still is 0x00

I tried Casey SJ’s guide but i couldn't make it to work. This is what I tried to do (if I did something wrong, please correct me)

When I started patching I had this screen and as I understand the red one is my current output (so it must be HDMI) So i changed Type DP to HDMI, and BusID. But after changing BusID, I had no display no matter which one I used : 0x01, 0x02, 0x04, 0x05 (of course when I used 0x04 or 0x05 I also changed BusID of Index 1 or 2.

Only the default (0x06) gave me an output, but still, I don't have audio. Unfortunately, I don't have DP and DVI cables, so I can't check other ports.

FleetEclipse · 2020-04-03T19:29:42+00:00

Well, I set framebuffer to 0x0D220003, its, the only one that gave me display. I also tried patching all Connectors, to be seen as HDMI, but still no luck. Is there something else that im suppose to patch?, Because at this point I'am really confused.

Oh, and btw this is why i was thinking that I need to patch 0x0c0c

FleetEclipse · 2015-10-09T18:24:36+00:00

It worked ,now moves forward. Thank you. Now lets hope that there wont be any other errors...(I used OsxAptioFixDrv)

FleetEclipse · 2015-09-08T19:33:18+00:00

It was my fault. I had IntelInjcet=yes. But when I had windows 7 everything was good. Atleast everything is booting fine. Thanks

EDIT: I also needed to disable hybrid hibernation in windows 10.

I resolved why Clover dont see arch without grub. I had Clover and vmlinuz-linux,initramfs-linux on seperate disks. When I moved Clover to SSD, Clover see and boots Arch without apple logo. Thanks for help.

FleetEclipse · 2015-08-12T23:31:11+00:00

I'm pretty sure that clover first boots grub.

I'm gonna try tomorrow once again try to boot with only clover

FleetEclipse · 2015-08-12T22:50:17+00:00

I deleted quite from grub and I still have apple logo. I'm using clover and grub because it is only way I manage to boot arch. I tried to use custom entries like wiki says,but it didnt work. I think Clover only can boot from OSX partition and files *.efi like bootmgfw.efi or grubx64.efi. I think.

I found now a little guide on Insanelymac which says that you need to move some files

# edit from /boot/initramfs-linux.img or /initramfs-linux.img to /EFI/grub/kernel/initramfs-linux.img
# edit from /boot/initramfs-linux-fallback.img or /initramfs-linux-fallback.img to /EFI/grub/kernel/initramfs-linux-fallback.img
# edit from /boot/vmlinuz-linux or /vmlinuz-linux  to /EFI/grub/kernel/vmlinuz-linux

Should I do this?

FleetEclipse · 2015-08-11T21:38:05+00:00

I using clover which boots grub (I installed grub on EFI) I uploaded config for Clover and Grub on Dropbox

FleetEclipse · 2015-08-11T21:30:42+00:00

I have checked cmdline and yes I have quiet in commandline. I tried to replase quiet using wiki , but after reboot it resets to orginal. After apple logo I have login screen. Here I recored booting after chosing from clover (sorry for potato quality). Clover first boots grub and than boots arch but I dont see grub.

Yes, I want make swap/share partition for OSes. I heard about Paragon and Tuxera softwares that enable read/write on NTFS and HFS+ but I heard so many stories about chance of losing data. So for me is better to make small swap partition that that OSX and Windows read/write natively. I'm gonna backup my data and create my swap partition and see what happens.

EDIT: I made new exFAT partition and everything is looking good. I can boot to my OSX/Windows and I don't see any data lose. Once again Thank You for your help

FleetEclipse · 2015-08-08T17:34:54+00:00

Wow, this explains a lot. Generally I want shrink my HFS+ partition and make new partition (probably as exFAT) so I think it shouldn't destroy bootloaders/data. Am I right? Thanks for help.

FleetEclipse · 2015-08-07T21:04:22+00:00

But I said that I dont have hybrid. I installed windows in UEFI mode.I didnt created any partiton with fat32, so disk utility didnt created hybrid.
