AMD Radeon HD 6870 no audio HDMI

[toleda]

I tried ssdt but not working, and I deleted.

Wrong answer.

What should I do?

Extract and compile DSDT, and after adding HDMI support?

 

[toleda]

What should I do?

I use ssdts (HDEF, HDAU, LPCB, ARPT, GFX0, etc.) on all my machines so I don't have to mess with dsdts.
Impossible to fix what was done incorrectly by removing the ssdt.
What do you want to do?

What do you suggest me?

SSDT was not working, and I've just taken off from /extra.

SSDT was not working, and I've just taken off from /extra.

Read the ssdt install instructions; rename SSDT-2.aml to SSDT.aml and install as Extra/SSDT.aml
To be clear, you will not know if it is working or not.
This the first step of many to get AMD HDMI audio working.

I use chimera boot loader.

SSDT It works best with Clover?

Works with any bootloader.

I'm sorry, but I'm an idiot.

The ssdt_hdmi-hd6670-P0P1, stop start to black screen, and I removed.

But only now I saw that report IORegistryExplorer marks AMD to P0P1.

I put the ssdt_hdmi-amd/nvidia-P0P1 to /extra
and now I get this, but with audio mute.

Any solutions?

No. HDMI audio is working.
