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

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

still have no audio.
Same boot log:
Code:
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.

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?

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

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.
