Hello,
the excuse my English.

I built a new installation, with a MB DH67CL Intel and a graphics card AMD Radeon HD 6870.

It seems that everything is working fine except the HDMI audio.
I tried different solutions but no result, what can I do to get the HDMI audio output from the HD6870.
Thank you.

HDMI audio is enabled with dsdt edits or ssdt injection, see Post #1, HDMI Audio AppleHDA
For support, see Post #1, Problem Reporting; attach requested files.
Sapphire HD6870 Vapor X (DP x2) is native, all other version need kext edits; see audio_hdmi_guides

Hello Toleda.
Thanks again for the previous installation, everything works fine.

I followed the instructions:

I put in extra: SSDT-2.aml: (GFX0) AMD/Nvidia discrete graphics (renamed SSDT.aml)
and not working

I put frame buffer Duckweed:
<key>AtiConfig</key>
<string>Duckweed</string>
and not working

My card is Sapphire HD6870, I attach IORegistryExplorer report.
thank you
