Thank you toleda for taking time time to troubleshoot these audio problems. I ask for help only after exhausting the limit of my technical ability.

This is a new install of a ASUS VII Impact... High Sierra using Intel graphics (Nvidia seems a bit problematic). The audio WAS working this morning as I continued to transfer my applications (only) over from time machine although I can't say when I noticed the icon became greyed out.

I've "updated" the HS install to get a fresh copy of AppleHDA.kext thinking it got messed up somehow.... I've only used the audio_cloverALC-130.command to install. I have attached all the requested data for your analysis.. Please take a look whenever you get the time.. Thank you so much.. jeff

N.B. I have no DSDT or any other files in ACPI folder... kext/other/ contains apfs.efi , AppleIntelE1000e, FakeSMC,realtekALC, and USBInjectAll

attached all the requested data for your analysis

Installed over a previously install audio method, conflict results in no audio.
See AppleHDA Realtek Audio/Post #1/X. Uninstall AppleHDA Realtek Audio/2. pikeralphaALC
Remove pikeralphaALC
Restart
Run cloverALC
Restart
If no audio, reply with new files

 

[Wingfat]

Thank you for your help. Unfortunately after following your guidance I still have no audio. Attached are new files as requested.. Thanks!

 

[toleda]

still have no audio.

Same boot log:

Kext with invalid signatured (-67030) allowed: <OSKext 0x7ffbff20f580 [0x7fff89b5d5b0]> { URL = "AppleHDALoader.kext/ -- file:///Library/Extensions/AppleHDA1150.kext/Contents/PlugIns/", ID = "com.apple.driver.AppleHDA" }
Kext with invalid signatured (-67062) allowed: <OSKext 0x7ffbff20d640 [0x7fff89b5d5b0]> { URL = "AppleHDA1150.kext/ -- file:///Library/Extensions/", ID = "com.PikeRAlpha.driver.AppleHDA1150" }

pikeralphaALC is still installed, no audio.
Remove L/E/AppleHDA1150.kext, see Post #4

Audio was working well for me for a week or so after updating to High Sierra. Today out of nowhere it stopped and I haven't been able to get it back. I haven't made any changes to my clover config or installed any new software or kexts, so I'm pretty confused as to what's going on. I currently have no audio devices (other than my webcam as input).

All of the requested problem reporting files are attached, with the exception of "Copy Of Console/All Messages (last boot)", as I can't seem to get the High Sierra console to show anything before the moment I open the app.

Thanks for all the work you put into this, Toleda.

 

[eak11611]

Huh...all of the sudden I have audio back. I've rebooted 10 or so times in a row with no changes and the last one "fixed" it. Is there something in my config that might cause audio to be flaky like this?

 

[toleda]

Today out of nowhere it stopped

all of the sudden I have audio back

Rebuild kernel cache: Terminal/sudo touch /System/Library/Extensions && sudo kextcache -u /
Remove duplicate ssdts in EFI/CLOVER/ACPI/patched
No mention SSDT-PTS.aml in boot log, purpose?
USBInjectAll.kext is temporary, remove when custom usb ssdt is installed.
config.plist had a problem cloverALC fixed

 

[eak11611]

Thanks for all that. I'll keep an eye on it and will update if the issue returns.

FWIW, the duplicate SSDTs were the .dsl files and the .aml files. I just keep both around in case I need to make changes later. SSDT-PTS was temporarily removed for testing other things, not related to this stuff.
