Mavericks: HDMI Audio - AppleHDA
1. dsdt edit: something was not done correctly, 2 PEGPs. Discard the edited dsdt. Edit the native dsdt with the same patch.
2. unrecognized HD6870, default framebuffer: Find the framebuffer (with HDMI) that loads, see ATI/AMD 5xxx & 6xxx Graphics Cards Framebuffer Personalities. The best choices are Duckweed, Lotus and Gibba. If still no HDMI audio, the working framebuffer has to be edited, see Lion HDMI Audio - Part 3a: Kext Edits - AMD. Download the Case Studies pdf for more info.
