I've noticed now that there is an occassional connection to the TV. After it's been black for a while, it will flicker and then for a brief second show the screen properly, then go back to being black or flickering. Is there something wrong with my config.plist? It seems very odd that this only happens when I'm not using the HDAS2HDEF patch.

It appeared that some of the 10.12.6-KBL-5912000-Port_0x*-DP2HDM patches were in there multipe times, so after cleaning it out, the machine actually booted and showed the desktop (and I could choose LG TV as output) for a few seconds, but before I managed to test anything, the screen went black again and the tv lost connection. Do you have any idea what might be wrong?

UPDATE: Turns out that it went all flickering and black, because the HDMI can't do 4K@60hz without the HDAS2HDEF patch apparently! So not sure what step to take from here...

UPDATE2: I'm using an HDMI to DP adapter now and it works. 4K@60Hz with audio, no screen flickering or anything anymore either, so I guess I'll just use that. Thanks a lot for the help, Toleda.

See Post #3296. Off topic.
Yeah, it is indeed pretty absurd. The only semireasonable explanation I can think of is that there wasn't bandwidth enough to support both 4K@60 Hz when audio got enabled. Either way, I'm fine with using the DP to HDMI adapter, so I'm out. Thanks.

Reboot with only main monitor connected
Reply with all new files

Ok, here we go. Same audio issues with only the main "DELL U3417W" monitor attached via mDP. All new files attached.

Also, not sure if off topic is okay, if not please ignore and I will post elsewhere later. I am now having trouble waking the computer which is a new problem since troubleshooting the audio issues. The computer will wake up, I can enter my password, then the computer freezes.

I tried almost everything in this site, two days suffering.:banghead:
I was not getting any progress. o_O
Until I read a post about removing Voodoo.
My problem was VoodooHdaSettingsLoader.
After removing it, everything worked.
Hope it can help someone.

Agree. HDMI audio is configured properly. IOReg shows macOS does not support your graphics card for either DP or HDMI audio.
Thanks. Does this have anything to do with why I can't load any video or music services? Or, do I have bigger issues lingering?
