[Solved] HDMI Audio doesn't work on Radon HD7770

[MarkusP87]

Hello,

first of all, this is my first Hackintosh and I don't got that much knowledge about Drivers and Kexts.

I'm trying to get the Audio on HDMI port to work without success so far.

What I've tried and/or used:
Used This Guide to get HDMI Audio which didn't worked.
I used the SSDT provided in the Guide and also tried with my own DSDT incl. SSDT patch.
The Theory seems to work because after I restart with the patched SSDT I see a new Entry in IOREG called "HDAU".
But I don't have any new Audio Sources to choose from.

I'll include Pictures to see what I've done so far and how it does look before/after patch.

Maybe someone could tell me what I'm doing wrong.

My Specification:
Intel Core i7 7700k
ASUS ROG STRIX Z270F Motherboard
16GB DDR4 Corsair Vengeance LPX @ 3000Mhz
Samsung 850 EVO 256GB SSD
ATI Radeon HD7770

Thank you so far for every reply!

best regards,
Markus

Hello,



I've got it to work !



i was always thinking that the System defined the Framebuffer for my Graphic Card which was the main reason that everything failed.



I was using a config.plist from another guy which had a different Graphic Card and therefore used a specific Framebuffer.



After changing the Framebuffer to the correct corresponding ports the HDMI Audio started to work!



To the conclusion I came trough This Guide.



best regards,

Markus
