For me delay did not work. I generated SSDT-HPET with SSDTime from linux. I added the generated SSDT-HPET.aml and patch to my OC but it did not work either.
Today, I saw your post about OC 5.9 guide for lenevo T440s in tonymacs and I used your SSDT and the patch to disable native HPET and finally the audio is working on my Lenevo X1 Carbon 3rd Gen.
Sniki, will it be possible for you to check my SSDT-HPET to see what was the problem?

I have the same machine as yours. Did HEPT fix by SSDT-time, with or without alcdelay, none of those could drive my alc292, and when i used the kextstat grep thingy in Terminal, logging showed that only com.apple.driver.HDAcontroller was loaded.
The disable navie applehept method is working perfer now on my machine, the only issue now is headphone noise
@undercoldwater
Same here, the audio worked after disabling Native HPET.
For headphone noise. you can try alcplugfix.
@festano92 What laptop and what codec do you have?
Listen, there is 2 condition about "Audio not working"
Speaker icon is GREY (there is no audio device output in audio preferences), this is caused by HPET and HPET patch is needed from Intel Broadwell and below. Intel Skylake and above don't need HPET patch. I assumed you have chooses correct layoutID after give HPET patch to make audio working
Speaker icon is available, and you can see internal speaker, etc in Audio preferences, but audio device give no output (it can give you output sometime / random reboot ). This is probably caused by other thing like COEF_INDEX and PROC_COEF.
So don't mix it about "not working audio".
HPET patch just for broadwell and below
@vit9696 and @black-dragon74 I finally managed to get audio working with OpenCore.
I tried with the available renames as mentioned on OpenCore Configuration.pdf for HPET fix but it didn't fix the issue although the patch worked (modified as needed by my ACPI set) I see that STA returns Noop but still no audio.
What i did is i added config.plist /Kernel/Block/ com.apple.driver.AppleHPET
As soon as i rebooted volume icon was non greyed out, and audio is working, also for some reasons, checking IOreg does still show AppleHPET loaded.
You may want to give this one a try @black-dragon74 just so we know for sure that it has no relation to AppleALC but rather a non-well configured ACPI as @vit9696 mentioned a few comments above.
Thanks
Off-Topic/Firm handshake note: holly crap the boot speed is nonsense/unbelievably fast with OC 0.0.4 + new AppleSupportPkg
Hi i was also able to get my audio working with that patch but i noticed something. I get a kernel panic when booting into recovery, updating macOS when this line is present. Do you have the same results also?
Same problem for me too, alc255
here with intel 9th gen (CFL+) laptop (layout id 27). I get this issue less frequently and whenever I get this, I just change the version of applealc kext, I mean I use different version of kext (debug and release versions are also considered different kext). recently I faced this issue and changed my kext to 1.6.8-RELEASE version. If some reboots/shutdowns after if the problem repeats then I would use either 1.6.8-DEBUG or completely different version like 1.6.6-RELEASE, changing the kext works. The issue is 1.
mentioned by @andreszerocross above. The thing is kext fails to load when the issue occurs
My motherboard have alc887 ok so whenever i run logic or ableton i hear some weird noices

That's really not a good idea. Of you want to do music production then buy an interface. Onboard audio isn't strong enough for that.
Hey, I would like to report an issue with the
AppleALC
project that I am facing since the very beginning on my hardware (ALC 295
). I didn't bring it up before as I wanted to test everything before opening an issue.The workings of the software is completely random. It sometimes works, sometimes doesn't. I have the logs from the event when it works and when it doesn't:
Logs when it doesn't work:
Logs when it works:
We can clearly see that for some reason
initializePinConfig
method is not being called. The result is no Audio input/output devices.The way to get back the audio is: Keep rebooting till you don't get it back. Which is a really dumb way to solve any problem. I have tried with all different layout IDs supported for
ALC295
. The result is the same.I have also tried with warm-booting and cold-booting. The results are exactly the same. Sometimes it works, sometimes it does not.
I have no other audio patches in place so there is no way anything else could be interfering with the workings of
AppleALC
I have tried every possible options and quirks and am not able to solve this. Hence this issue.
I would be glad to provide any help I could for further research.
Warmest Regards
