Attached the new files, thank you for your patience Toleda.
No change, reinstall onboard. What HDMI device is attached? What does System Information/Graphics show for the 780?
The HDMI audio works, but when using the system loud static plays and freezes my system. What could be cause the problem?
I never heard of HDMI audio freezing a system; how did you determine the cause? I know what is in the dsdt if HDMI audio is working. An IOReg is useful, your system specs are helpful and the source and app you see the problem with are very important. Based on the info provided, static on digital audio, electrically and practically, not possible.
Still no HDMI Audio, attached the new DSDT and Ioreg. By the way i am not using any other injection except the DSDT, no HDAEnabler or Clover Injection (i put injection on NO, using Detect gives the same results).
IOReg/NVDA,Display-A@0/av-signal-type is wrong and audio-codec-info is missing. A test:
Ok, applied the patch on AppheHDA and on the DSDT (removed the HDEF edits from the patch file and replaced the ig-platform-id with my working one). Attached Ioreg (with HDMI TV plugged), patched DSDT, patched AppleHDA and the patch file i used for DSDT.
Remove S/L/E/HDAEnabler. Remove dsdt/HDEF/hda-gfx including the comma after the closing bracket on the line above.
