No audio with Realtek alc269

Hi,

i also made a codec dump as you mentioned and i also have "ALC271X", "Vendor Id: 0x10ec0269" so that means i need to work with "AppleHDA-272.18.1-ALC271x.zip" to get my audio?

Yes. ALC271X is a variant of ALC269.

No pasting involved.

Read the README for using MaciASL and the laptop repo: https://github.com/RehabMan/Laptop-DSDT-Patch

i edited the dsdt and got error "object does not exist (dtgp)" then i fixed this error and install the hda.kext with kext utility but still don't have sound. somebody said in previous post that he did something with rehab man's layout id nad IRQ fix. i patch IRQ but don't know what to do with "Layout ID" .

My patches do not use DTGP.

The _DSM method you're using is wrong.

            Method (_DSM, 4, NotSerialized)  // _DSM: Device-Specific Method
            {
                Store (Package (0x0C)
                    {
                        "built-in", 
                        Buffer (One)
                        {
                             0x00                                           
                        }, 

                        "layout-id", 
                        Unicode ("\x03"), 
                        "PinConfigurations", 
                        Buffer (One)
                        {
                             0x00                                           
                        }
                    }, Local0)
                DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
                Return (Local0)
            }

The package size is defined at 12 entries (0x0C), but only 6 follow. OS X will ignore it.

Use "Audio Layout 12" from here: https://github.com/RehabMan/Laptop-DSDT-Patch, change the 12 to 3.

Your DSDT also lacks "IRQ Fix" (available from same repo above).

It is all covered in the guide: http://www.tonymacx86.com/yosemite-laptop-support/152573-guide-patching-laptop-dsdt-ssdts.html

IRQ Fix mean "system_IRQ.txt" in the patches ? (if yes, i applied it)


whenever i apply the "audio_HDEF-layout12.txt" and save it after changing layout 12 to 3. it goes back to old state if i try to close and open the DSDT. is that normal?

sorry about that whatever it shows at the time after saving it. i restarted computer and sound is working even my fn keys are working for sound. this is great. i did't know that that could be so easy thanks for your help.

how did you determine that layout id should be "3" because when i check info.plist it show 42 layout IDs?
