Nice work, hdmi audio ok with nvidia gtx 960 y El capitan.
Thanks

Gracias por todo realmente sencillo para mi primera instalación. I5 4460/gigabyte h97n wifi/nvidia 960 con unibeast 6.0
 
I tried the X99 BR3A SSDT and it didn't work for me. It shows 2 HDMI/DP outputs under Intel HDA under audio system profiler, but nothing under the actual devices tree and I can't pick it as an output in Sound Prefs either.

My path was just slightly different because of a different port I assume at NVDA,Display-B@1
 
Yeah sorry I loaded it from your later post in this thread. Here is my IOReg.

S/L/E/HDAEnabler1.kext interferes with HDMI audio, remove.
1. Onboard audio, install ssdt_hdef-1-x99_alza.zip, confirm 1150 audio working.
2. Nvidia HDMI audio, install the BR3A ssdt from Post #7.

I made the requested changes. Deleted the kext and installed the Alza ssdt. Rebooted and audio still worked under intel HDA there was no HDMI. Installed BR3A ssdt and rebooted again. Audio still worked Intel HDA showed HDMI but wasn't under output devices and not selectable in sound system prefs. Attached is the IOreg after the changes.

Thanks for the help!
