The DVI-D > HDMI worked in one of the DVI ports. Wow! So, I am seriously considering returning this video card and trying another one what has more DP and HDMI connections. I do not like the idea of using these adaptors.


I have submitted my files in a previous post. Is there some way to reroute the audio though the DP?

Thanks again.

Where did you get SSDT-HDMI-NVIDIA-HRU4.aml? Remove.
Why is both SSDT-HDEF-HDAS-1.aml and SSDT-HDEF-HDAS-2.aml installed?
One or the other, not both.
Install SSDT-HDMI-NVIDIA-PEG0.aml
Reply with new files.
Thanks toleda,

That fixed my Problems at all! All Audio is now working. No idea where I had that HRU4 file, maybe it was causing the problem. After reinstalling PEG0 with all y it's working fine!

If you still need my files to look at it for problems with other people feel free to ask.
Thanks again! :)

Hi!

First I wanted to thank toleda for his excellent post.

I have been able to make audio work... with speakers or headphones, but hdmi audio on my tv (LG32LB75) does not work...

My computer has the following configuration:

OS X: Sierra 10.12.4

Method used: cloverHDMI

MoBo: Asrock h170m itx/ac
CPU: i5 6500
Graphic card: EVGA NVIDIA GTX 1060 6GB
16GB RAM DDR4

I can connect the computer to the TV screen either with hdmi connector or with a dvi-d to hdmi connector. neither of them work unfortunately.

I could use some help :) if possible

I am trying to pick a method and could use help. the cloverHDMI section only talks about hdmi audio, so I assume thats the wrong section. The next section says "OS X HDMI and/or DP audio support:" and since it says "DP" I assume its the right section. I think the right instructions are in the section called "OS X HDMI Audio Guides". As I understand I will have to pick A1 or A2 and then do B and C. unfortunately the tables for A/B/C isn't updated for Skylake or Sierra. It seems like people are getting it to work though so I'm hoping after I select a method people will be able to advise on the various bits for Skylake and Sierra.

I am new to both SSDT and DSDT editing. I suppose I'll try the SSDT method since it will survive BIOS updates. However I'd also like to run piker alpha's script for more cpu power states. How do these play together? Should I just generate them independently and then combine them in a text editor or something?

Well I can't fill out any of the other help request stuff till a method is picked. Thanks in advance for any help!

Try DP2HDMI adapter

I have bought one, just waiting for it to arrive. The point is that when I have the mackintosh connected through DVI2HDMI, it does not work, for sure. But once I have already started it up, and then I switch from DVI2HDMI to simply HDMI2HDMI, it works (sometimes) and LG32LB75 appears as one of the audio devices. So, it should not be necessary to use any DP2HDMI adapter... I guess, I have also considered buying speakers, which work for sure.

Any suggestions??
