Audio - HDMI Audio AppleHDA [Guide]

[Tsur]

toleda,

I just had to post and give a HUGE thank you for putting together this guide. Thanks to your considerable effort, I now have surround sound through the display port on my Lenovo TS140 (i3-4130, built-in 4400 graphics, Yosemite, Clover).

It took me a couple of days, and more than once I almost broke down and posted for help, but I made it. Looking back, I made it much more difficult than need be. If I had to do it again, I'd be done in 30 minutes - easy peasy. For me, the biggest challenge is wading though the mountain of data that isn't applicable to one's rig.

One suggestion - if you ever get around to updating the guide, say when 10.12 comes out, I think some Roman numerals and lowercase letters could really help out. Not just for the person using the guide, but for people providing support and answering questions. For example, you could just write, "The directions and files are at III. C. 2. i. a."

Thanks again for the guide and all the work.

unable to find HDAU@3.

Where did you get config.plist?
Delete every property with a #
No idea why ssdt works for IGPU and does not for HDAU.
Reply with fixed config.plist and new files.

Thanks for the suggestions. The site editor only allows bullets or numbers. Most pdf guides use Step 1, 1., a., i.

The config.plist file was from the Clover installer.

I used the installer to get a fresh new copy of config.plist, removed the keys prefixed with #, applied the patches to KernelAndKextsPatches/KextsToPatch and added Device/Audio/inject = 1. No HDMI output in the sound pref pane.

My Clover Installer/config.plist does not include any #s.
2nd request, remove all #properties.

Appears I misread your instructions. I thought I was supposed to just copy the KextsToPatch properties from your config.plist into my own config.plist.

Instead I replaced the entire config.plist with the one in config-hdmi_hd4600-100.plist.zip. It removed all the other sound outputs in my sound pref pane but added an HDMI output which is the only one I needed.

Thanks!

I can confirm that the framebuffer that is working for HDMI+DP is : 0x16120003

You confirmed DP audio works on a HDMI connector and HDMI audio does not work on a DP connector. System Preferences/Sound/Output should show HDMI and DisplayPort not HDMI x2. At your convenience, edit Port 0x7 from HDMI to DP (switch the two connectors) and reply with new sysprefs screenshot and IOReg.

My confirmation was a Framebuffer that worked with HDMI/DP and now DVI. I can clearly see your precision that my DP(default framebuffer connector) was actually an HDMI connector and the HDMI port was in fact a DP connector. Corrected thanks.
DP(Port0x7) and HDMI(Port0x6) connectors switched, DP is now DP connector with audio.
The only sign of mentioning DisplayPort info is in system report/audio : HDMI / Display Port.

helped me long time ago to switch the "rear" output with "headphones" output, at the back of the motherboard.
