Radeon 6870 HDMI Audio in Lion

[trboteg]

Does anyone have HDMI audio working in Lion for the Radeon 6870? Any help would be appreciated. I've searched and searched, but can't seem to find anything for Lion.

If you have a Sapphire HD 6870 and use the Duckweed Framebuffer, no kext editing is required. With the DSDT edit above, HDMI audio works out of the box in Lion.

 

Please see this post for editing the HD 6870 Framebuffer bcc9

Good luck.

Where can I download the "Duckweed Fframebuffer"?

I have the same problem, no audio over HDMI, and I don't understand what I should do or what you mean with the post above...

Duckweed is in Ati6000Controller.kext. See bcc9 post. Lion hdmi audio requires the dsdt edits and kext edits described above for the Sapphire HD6870 Vapor-X. Framebuffer edits are different by manufacturer. 6870 hdmi audio device ids are supported natively in Lion.
