[solved] ALC668 - AppleALC - not working

[speedyrazor]

Hi, On my Dell XPS 13 9333, I have previously been running High Sierra, just upgraded to Mojave, sound stopped working with patched HDA, now trying to get AppleALC working. I have removed all previous audio patches (I think), restored a fresh Mojave AppleHDA kext, have the latest AppleALC.kext and Lilu.kext, but still unsure what I am doing wrong, if someone could point me in the right direction please? Debug logs attached.

Regards.

You are injecting layout-id=1. It is not valid for AppleALC, ALC668.

Yes, I wasn’t sure about that. Are you showing me what the correct layout IDs are below? If so, what is the correct layout ID?

That is the Info.plist from AppleALC sources (Resources/ALC668/Info.plist). It has the list of valid layout-id values. Please note that layout-id=1 is not one of them.

Please refer here, try all possible layout mentioned

Same as those listed in post #3.

Note: As a general rule, I trust source code more than documentation.

Thanks, I will try those and report back, just checking that I am putting the layout ID in the correct place / format?

There are many different ways to inject layout-id (Devices/Arbitrary, Devices/Properties, Devices/AddProperties, ACPI [patching or SSDT], Devices/Audio/Inject, AppleALC kernel flag 'alcid'). All of them, done properly, are equivalent.

Easiest is probably config.plist/Devices/Audio/Inject=<the-layout-id>

Sounds is now working, using layout ID 3. Thank you so much for the assistance.
