UX430 (kabylake refresh) and realtek alc-294

[xseignard]

Hello, I have an Asus UX430 (kabylake refresh) and it seems that I have a realtek alc-294 instead of realtek alc-295 mentionned in this repository.

I had troubles getting the jack output working (but it was recognized when I plug my earphones).

I updated AppleALC.kext from here (https://github.com/acidanthera/AppleALC). And started fiddling to find the right layout-id.

At the end, layout-id 21 is the one working for me.

So I created a file (layout21_HDEF.asl ) with the follwing (in src/hotpatch/include):

    // inject properties for audio

    External(_SB.PCI0.HDEF, DeviceObj)
    Method(_SB.PCI0.HDEF._DSM, 4)
    {
        If (!Arg2) { Return (Buffer() { 0x03 } ) }
        Return(Package()
        {
            "layout-id", Buffer(4) { 21, 0, 0, 0 },
            "hda-gfx", Buffer() { "onboard-1" },
            "PinConfigurations", Buffer() { },
        })
    }

And changed the src/hotpatch/SSDT-UX430-KabyLakeR.dsl to include the right layout (on line 9):

    #include "include/layout21_HDEF.asl"

Now I have working audio (jack + speakers)

I hope this help other people. I can make a PR, but since it seems there are UX430 kabylake refresh with alc-295, I wouldn't mess with it.

Hi.

I have an UX430 UAR with all-294 as you. And I also use layout 21 from the beginning without any issue (outside of the fact that there is no microphone with jack).

I inject Device Properties for codec configuration, one SSDT less :p.

            <string>onboard-1</string>
            <key>layout-id</key>
            <integer>21</integer>
        </dict>

Hello. I have UX430UNR with ALC294. To make my audio working, I updated AppleALC. Then on clover configurator I disabled patch that say rename HDAS to HDEF and change layout-id to 21. With this, I have jack audio. the microphone with jack is working too.

Hi.

You have the microphone for your jack headset working ? Internal microphone works, but external headset one not in my case.

[akaditya13]

Yes, microphone on my headset is works too. i confirm it with trying alternately build in and the headset. But, my headset only working system preferences-sound-input window is active. so wierd.

Hi @Vmonheros and @akaditya13 Does the jack output work after sleep/wake ?

Hi @xseignard The headset works properly for mic/out after sleep/wake.

I am using Multi system, Windows 10 and Hackintosh My problem, no sound after restart Windows 10. To fix this, is to shutdown the Windows 10.

Thanks @bliss95 but what's your asus model, realtek model, and your configuration ?

Thanks, what about the realtek chip ? Is it ALC294? What layout id are you using? Do you also have codeccommander ?

[bliss95]

Realtek ALC294, Layout Id is 21, other layouts don't work, New Layout Id 22 is coming to test in AppleALC 1.4.9. I have used CodecCommander before Catalina. Fixed the microphone issue. I don't know if there is still a need now. It just stands in the EFI folder.

Thanks a lot!

[bliss95]

AppleALC 1.4.9 is out. Layout ID 22 is the same 21. No difference except Codec Name in plist

Hello,

First of all thanks for this awesome work, I've got an Asus ux430unr and I've setup MacOs Mojave with little effort. What an experience MacOs!

How can I find what ALC I'm running ? And then, how can I update the correct layout ? I've read the instructions of AppleALC and updated the kext but still the headphones don't work.

Thank you ahead.

EDIT: I've found I have the ALC294 as you. I've followed your instructions and now I'm a happy user of a fully functional mac :)
