Intel NUC HDMI audio

IT WORKS in the second port

When convenient, test the attached AppleIntelFramebufferCapri.kext. It has been edited to provide HDMI audio on both HDMI ports. Installation:

1. Back up the current S/L/E/AppleIntelFramebufferCapri.kext
2. Copy Downloads/AppleIntelFramebufferCapri.kext to Desktop
3. Run KextBeast.
4. Restart

Verify HDMI audio on both HDMI connectors and reply with an IOReg.

i have NUC Thunderbolt model (BOXDC3217BY).
audio via HDMI is not working, but audio via Thuderbolt is working.
i tried your patched AppleIntelFramebufferCapri.kext, both HDMI and Thunderbolt is ok.

Thanks for the information. It confirms the patched AppleIntelFramebufferCapri.kext works on both versions of the NUC (2xHDMI and HDMI+TB).

If you are up for an experiment, I believe both ports will work native in a different frame buffer. Edit dsdt/GFX0/AAPL,ig-platform-id to 05 00 62 01 and edit device-id 62 01 00 00, install edited dsdt and restart. I am not sure if IGPU memory has to change.

There is no native framebuffer to support the the 2xHDMI NUC.

i changed AAPL,ig-platform-id to 05 00 62 01, device-id to 62 01 00 00.
i used oringal AppleIntelFramebufferCapri.kext and patched AppleIntelFramebufferCapri.kext, but HDMI audio is not working, Thunderbolt audio is working

My mistake. Interesting the port number is 0x0 rather than 0x5. The 01 framebuffer with port 0x5 as HDMI is for laptops (macbookpro retina). 0a patched is the best choice and works with both versions of the NUC.
