Ok back to normal

attachicon.gifShane's iMac.zip

 

Gives me time to work on my USB ports, Need to make sure i dont mess up my AIO liquid cooler, And i have one of these to take into consideration.

Are you using ADGP fix?

 

Not sure if this will work, but let's try it and see if it at least changes your device from PEG0 to PEGX (may result in black screen)...

 

17,1 SMBIOS seem to be touchy when it comes to SSDT injection

Bit of an odd one since generating the ssdt's the GPU information is missing on about my Mac.

See error reporting.

SSDT-GFX0.aml.zip

I'm not using it anymore but have used it on my system. I'll give the attached ssdt a go in a few minutes.

Haha, almost... missing hda-gfx from GPU props. Do you have HDMI audio?

I updated previous post that i have audio back but not hdmi audio.

Okay... one last attempt... try SSDT-GFX0.aml

 

If no sound, you have two options:

 

1. Switch to Mac Pro 6,1 SMBIOS and use the GFX-1 generated from ssdtGen

or

2. Stick with your custom DSDT.aml

 

As stated above, 17,1 SMBIOS is funky and not injecting properties properly.

Is there any benefit or loss in switching to mac pro 6,1?

 

Still no HDMI audio :-(

Switch to MacPro and i have hdmi audio straight away.

Couple of reboots later it's back :)

17,1 -- GFX0 has correct values, but HDAU is missing DigitalAudioCapabilites... not sure why though.

 

6,1 -- Switch to a generated GFX1 instead of GFX0 and see if it works, if not, you may need a custom SBUS as well since it is still missing.

I'll do that tomorrow it's too late now. Thanks for help so far.

If you run into issues with the generated GFX1.aml and SBUS.aml, then use the attached custom SSDTs.

SSDT-GFX1.aml.zip

SSDT-SBUS.aml.zip

Before i generate new SSDT's should i revert all back to default?

Rename _DSM to XDSM enable or disabled?

PegSsdt dropped?

nv_disable before generate?

Inject nvidia before gen?

NvidiaWeb disabled before gen?

Need XDSM patch. Best to keep PegSsdt dropped. Will need to use nv_disable to get into OS. Then, just generate GFX1.aml (build GFX1) and SBUS.aml (build SBUS) with the other generated SSDTs already loaded/in patched (just make you do NOT have GFX1 or SBUS in the patched folder).

Use this SBUS.aml...


AppleALC, Lilu and CodecCommander.

Layout 5 if that helps.

Ahhh that's why. I'm injecting layout 1. Updated GFX1 with layout 5 injected.

Do me a favor and switch to option 1, (you will need to copy the AppleHDA and AppleHDAController patches to your config.plist), follow instructions for installation, and then use the first custom GFX1.aml

 

Unfortunately, SBUS is still missing... will create another SSDT...

I have a development.

 

I thought id take a look at my config.plist just to double and triple check and i found this

So i unchecked it rebooted and HDMI audio is working.

I'll reboot again to make sure then send ioreg.

Ahhhh... that'll explain why. Might also explain why PEGP kept being injected.

HDMI audio still working.

Would you like me to remove dropping PegSsdt and see if HDMI still works and pegp gone plus gfx0?

I did it anyway and the results are good, pegp gone from ioreg and gfx0 in its place plus hdmi audio still working.
