Audio - HDMI Audio AppleHDA [Guide]

[toleda]

trying to understand how actually and what to do

See Post #1981 for method and 7750 example.
graphics card: number of physical HDMI and DP connectors?
radeon_bios_ decode: physical connectors connector sense_id?
ati-personality: framebuffer connectors sense_id?

Objective: edit HDMI and DP (if available) framebuffer connector sense_id to the same as physical connector sense_id
Use the 7750 example to layout the 7870 case.

I am currently using only HDMI port and Hamachi FB (don't know is it right or wrong but it's giving me same result as Futomaki), I want to make HDMI as my primary display
here is the info:

Connector configuration:
Personality: Hamachi
ConnectorInfo count in decimal: 4
Disk offset in decimal 1765536

Radion bios decode :
Connector at index 1
Type [@offset 42924]: HDMI-A (11)
Encoder [@offset 42928]: INTERNAL_UNIPHY2 (0x21)
i2cid [@offset 43051]: 0x91, OSX senseid: 0x2

Redshok bios decode:
encoder obj id [0x21] which is [INTERNAL_UNIPHY2 (osx txmit 0x22 [duallink 0x2] enc 0x5)] linkb: true
as per
http://www.insanelymac.com/forum/topic/303186-how-to-modification-of-amd-fb-clover-injection/page-1, as per this guide
Connector Type HDMI 0 × 00000800 = 00 08 00 00
didn't understand how to find port
I am very sorry for that, you are trying to guide me but didn't figure out the correct one as per your guide

with kind regards

2nd request, what connectors on the graphics card?
The link has dramatically more information than needed for your solution.
redsock_bios_decoder is not required
The connectors are noted in the link:
0×0400 : DisplayPort
0×0800 : HDMI

Suggest Futomaki rather than Himachi
As in the 7750 example, make a text file with ati-radeon decode output and the Futomaki frame buffer output and attach.

Hi Toleda and fellow hackintoshers...thanks for sharing your knowledge and taking a look!

Description of problem:
Nvidia HDMI audio works, Nvidia DP audio does not (not recognized by OS, option disappears when cable is switched)
Using active DP > HDMI 2.0 adapter to achieve 4k60 on Sierra

System specs:
10.12.1 (16B2555) / Asus Z170 Maximus VIII Hero / BIOS 2202 / 6700k / GTX 970

Procedure used:
audio_cloverHDMI-120_v1.0d.command

2nd request, what connectors on the graphics card?

physical connectors of my graphics card : 2 x DVI (1 Single Link, 1 Dual Link) 1 x HDMI 1 x DisplayPort but using only HDMI port

as per your suggestion I changed my FB to Futomaki

make a text file with ati-radeon decode output and the Futomaki frame buffer output and attach

IOReg shows HDMI audio working on HDMI connector. HDMI connector is HDMI 2.0
DP > HDMI 2.0 adapter ? Why?

Great.
Analysis (framebuffer):

Futomaki	VBIOS/sense_id	framebuffer/sense_id	edited connector
0x0	DP/1	DP/1	OK
0x1	HDMI/2	DP/2	HDM/2
0x2	DVI/3	DVI/6	OK
0x3	DVI/6	HDMI/3	DP/3
0x4	DVI/6
0x5

Fix/edit framebuffer to match VBIOS (same as 7750 case study)
Make connector 0x1 HDMI: 00 08 00 00 04 02 00 00 00 01 04 00
Make connector 0x3 DP: 00 04 00 00 04 03 00 00 00 01 02 01

Reply with find/replace edits for 2 connectors.

I use a 4k TV as a monitor. The goal is 4k resolution @ 60hz with audio.

HDMI = 1080p @ 60hz / 4k @ 30hz / working audio
DP > HDMI Adapter = 4k @ 60hz / no audio

The adapter has been verified working in other OSes with same hardware setup.

 

[toleda]

HDMI = 1080p @ 60hz / 4k @ 30hz
verified working in other OSes

GTX 970/HDMI 2.0: 4k @ 60hz
other OSes, not relevant

GTX 970/HDMI 2.0: 4k @ 60hz

Understood, merely verifying that the adapter hardware is not at fault.
