Realtek ALC3228

Hello.

I have an All In One HP Pavilion with MacOs Sierra installed and not have sound for HDMI.

Intel Core i5-4460S
Graphics Intel HD4600
Realtek ALC3228-CG
8 Gb Ram
SSD 120 Gb

I am using VoodooHDA 2.8.8 with which I have sound so much as by external jack internal speakers.
Also I works perfectly the microphone internal as input by jack external.

It only that not have been able to get is the audio HDMI.

Any suggestions if there are chances of getting HDMI audio, please?

HDMI audio usually requires a few things in DSDT:

1) that the iGPU section injects a reference to hda-gfx

2) a device HDAU section

 

If you already use a patched DSDT, please post it. If you do not, extract it your raw table from BIOS and post it too.

 

If you have all that but no HDMI audio, you may have to switch to patched AppleHDA. To that effect, start by using DPCIManager to identify your codec.

Hello Hervé.

 

I do not use patched DSDT since I use Clover UEFI as bootloader.

 

I have HDMI audio by adding the AppleALC.kext to the EFI/Clover/Kexts/other folder.

 

But to make it work I have to eliminate the AppleHDADisabler.kext and the VoodooHDA.kext and restart the computer.

 

What do not want is having to be deleting and copying the VoodooHDA kexts whenever you want to use the HDMI audio, if possible, of course.

 

Best regards

You cannot have patched AppleHDA and VoodooHDA at the same time; it's either or. HDMI audio is usually supported with patched AppleHDA, much less frequently with VoodooHDA (or you need a very recent version).

 

You stil have not advised on the codec built in the ALC3228 chipset.

Ok, Thanks for reply I will continue working in this.

Best regards
