Lost HDMI Audio, PB 4740s 10.10.4, PBI 6.3.9

[Don_Grappler]

Please help.

I lost HDMI Audio output, likely (did not log my updates) after running 10.10.4 update and PBI 6.3.9. Have fumbled around with combo update, reinstall, and other stuff...

No idea what is wrong. Nor how to fix it.

Give me troubleshooting files too. What is your screen resolution?

 

[Don_Grappler]

Files without installing anything again are install.log and PCI.txt: View attachment Troubleshooting 2015-08-12 13-50.zip

Internal screen is 1600 x 900, external varies (mostly 1920 x 1080, also 726p).

Thanks for your readiness!

EDIT: now the external HDMI screen ist not recognized after sleep any more. is some sadistic hacker messing with my head!?

The ioreg is corrupt.

Download patchmatic: https://bitbucket.org/RehabMan/os-x-maciasl-patchmatic/downloads/RehabMan-patchmatic-2015-0107.zip
Extract the 'patchmatic' binary from the ZIP. Copy it to /usr/bin, such that you have the binary at /usr/bin/patchmatic.

In terminal,

if [ -d ~/Downloads/RehabMan ]; then rm -R ~/Downloads/RehabMan; fi
mkdir ~/Downloads/RehabMan
cd ~/Downloads/RehabMan
patchmatic -extract

Note: It is easier if you use copy/paste instead of typing the commands manually.

Post contents of Downloads/RehabMan directory (as ZIP).

Also, post ioreg: http://www.tonymacx86.com/audio/58368-guide-how-make-copy-ioreg.html. Please, use the IORegistryExplorer v2.1 attached to the post! DO NOT reply with an ioreg from any other version of IORegistryExplorer.app.

And output from:

kextstat|grep -y acpiplat
kextstat|grep -y appleintelcpu
kextstat|grep -y applelpc

Also, post EFI/Clover folder.

This should be the right ioreg, and the other data.

Don't hesitate to tell me if I did something very stupid, so once will be enough.

Is this config.plist from PBI-CE? It does not have a correct patch for HDMI-audio. Ports are patched in 0x1660004 to enable HDMI-video, but not to change the connector-type from <00 04 00 00> to <00 08 00 00>. HDMI-audio not expected to work without connector-type patch.

That was it!

I replaced the config with a working version from backup (a .dmg of the EFI partition) and sound is back.

Thank you so much!

Will fix in new PBI CE

First check if it's not OK already.

Problem could have been my fault, playing with Clover configurator.

It's my fault mítaking dp and hdmi patches for hd4000. Fixed in 6.3.9.5
