<< Solved >> Trying to get 5.1 HDMI output on High Sierra

[Hypersleep]

it will look like:

<key>Boot</key>
<dict>
<key>Arguments</key>
<string>nvda_drv=1 alcid=1</string>

your motherboard will tell you what audio codec you have in the form of ALC****

Thank you!

I'm still not having success though.

I have determined my motherboard uses Realtek ALC1220.

The available layout numbers are quite a lot!

Looking at the info.plist comments on the 'supported codecs' page you linked, I have a feeling that number "1" should have worked, as it seems to match the inputs/outputs I have on motherboard - but it didn't.

I tried 2, 3, 5, 7. I then tried 27 & 30, only because I noticed that they are related in some way to Z370 chipset in the info.plist.

I thought I'd better check in before cycling through the remaining 17 numbers to try, I have a feeling it would be a waste of time, I feel as if there's something else going on.

I have snapped some photos of my desktop. Could it be related to the VoodooHDA somehow, which I seem to have at one point installed but doesn't seem to be doing anything? How do I remove anything that might be interfering and get back to a basic AppleHDA kext?

It seems to me I tried various different things before just to get my Scarlett to function, maybe without enabling audio onboard properly via motherboard?

Thanks for the help again.

you would only use AppleALC (recommended) or VoodooHDA (if you are unable to get AppleALC.kext working)

in terminal do this command and copy and paste the result here:

sudo kextcache -i /

Here is the result:-

remove your hackintosh kexts from /Library/Extensions and make sure they are in your EFI/Clover/Kexts/Other folder

delete VoodooHDA.kext

I have some progress - thank you!!! I'm still not hearing anything throught the HDMI cable though. Here's a pic of what outputs I now have:-

So, the question is what do I do next?

Do I need to do the framebuffer part?

Or is there no HDMI support via graphics card, but rather only through motherboard HDMI slot? Hmm...

framebuffer is only for intel, should not be required for nvidia hdmi

you could try setting ResetHDA to true in your config.plist:

Configuration

Bootloader for macOS, Windows and Linux in UEFI and in legacy mode - CloverHackyColor/CloverBootloader

I totally forgot when I replied that I had still aclid=5... so I began to cycle through the numbers again. I still have no HDMI out, but 2 new 'line out' audio output entries appear on certain numbers, and on one aclid setting it appeared 3 times. There's no audio when I point VLC to these devices though. The numbers I've tried so far are:- 1, 2, 3, 5, 7, 11, 13, 27, 30.

I did ResetHDA to true, but doesn't seem to have changed anything. It seems I have no option now but the cycle through every single aclid number and cross my fingers that one of them is correct. I'm still wondering if my HDMI cable needs to be connected to motherboard HMDI slot rather than graphics card HDMI slot (which it is connected to currently), due to the part in the guide which mentions "Nvidia: NVCAP configures all connectors. no macOS support for 2x HDMI".

I will report back once I have cycled through every single possible aclid number, unless you have any other suggestions... The possible numbers are 1, 2, 3, 5, 7, 11, 13, 15, 16, 17, 20, 21, 25, 27, 28, 29, 30, 34, 35, 98, 99, 100. So it might take a while!!!

if you want to use your intel onboard graphics, then you plug the hdmi cable from monitor to motherboard and then setup the framebuffer patches


or just use hdmi from monitor to nvidia card and then the speakers on your monitor should just work

Hi Feartech!

I've just had unexpected success!

Instead of cycling through all the possible layout ID's, I remembered about the Hackintool and where I got up to under Method 2 in the Lilu Idiots guide, before getting stumped by trying to run VoodooALC unnecesarily. I could see that it seemed to hint strongly that layout 7 was the correct one, so I set it and generated the patch, copied and pasted into the relevent section in clover config file.

Reboot and I can see HDMI output as available (all the other line-outs and optical seems to have disappeared, but I don't mind since it's only the HDMI one I really want).

A MASSIVE Thank You! At the very least I feel like I owe you a beer.

glad you got it sorted!

the applealc is really for your internal speakers
