This kext with this DSDT HDEF code works well

Device (HDEF)

        {

            Name (_ADR, 0x001B0000)

            OperationRegion (HDAR, PCI_Config, 0x4C, 0x10)

            Field (HDAR, WordAcc, NoLock, Preserve)

            {

                DCKA,   1,

                Offset (0x01),

                DCKM,   1,

                    ,   6,

                DCKS,   1,

                Offset (0x08),

                    ,   15,

                PMES,   1

            }

            Method (_PRW, 0, NotSerialized)

            {

                Return (GPRW (0x0D, 0x04))

            }

            Method (_DSM, 4, NotSerialized)

            {

                Store (Package (0x08)

                    {

                        "codec-id",

                        Buffer (0x04)

                        {

                             0x92, 0x08, 0xEC, 0x10

                        },

                        "layout-id",

                        Buffer (0x04)

                        {

                             0x01, 0x00, 0x00, 0x00

                        },

                        "device-type",

                        Buffer (0x0F)

                        {

                            "Realtek ALC892"

                        },

                        "PinConfigurations",

                        Buffer (One)

                        {

                             0x00

                        }

                    }, Local0)

                DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))

                Return (Local0)

            }

        }

If you want, you can use HDAEnabler with layout1 instead of DSDT Injection

I used your attached AppleHDA kext but no sound.How to use HDAenabler using layout 1 ?

Thank you

Clic on "Download.zip" and install HDAEnabler1, repair permissions and reboot

Ok i downloaded and installed the HDAenabler1.kext and repair permission using kextwizard and reboot.But still same no audio and i see only "Audio ID: 1"  on system report.

Thanks

I am sorry ! I deleted HDAenabler1.kext and put this DSDT.aml into EFI/CLOVER/ACPI/patched and i get appleAcpiplatformExpert : : Start Failed - System uptime in nanoseconds kernel panic. :(

Ok, i think the dsdt you posted in PM is not for your system; boot Clover without any option for ACPI section, delete all ACPI tables from ACPI/Origin and ACPI/Patched folders, reboot and extract the dsdt with this terminal command:

 

perl -e 'open(CMD, "ioreg -lw0 \| grep DSDT|") or die; while()
{ chomp; if($_ =~ /\"DSDT\.?\d?\"=]*)>/) { $buff = $1; open(PIP,
"|xxd -r -p > ~/Desktop/dsdt.aml") or die; print PIP "$1"; } }'

 

You find dsdt.aml in desktop; compress and attach the file.

 

What is the motherboard on which you want to run ALC892?

Try ths

Hi,

 I get kernel panic as before and now i will try the above kexts. Many thanks for your effort.

AppleHDA to Yosemite can be found here: AppleHDA for Yosemite - DP1

Do i need to use HDAenabler with this ? because its not working if i install only AppleHDA.kext

I used this kext for ALC892 (10.9.3 kext patched by toleda), and changed the key "Device / audio / inject" in config.plist to 1, now it works great for me.

Can you post your config.plist , audio part only ?

Sure, here you go (pasting entire Devices section). The only change I've made from the default installed one is to set the Audio / Inject value to 1:

 

 

 

	<key>Devices</key>
	<dict>
		<key>Audio</key>
		<dict>
			<key>Inject</key>
			<string>1</string>
		</dict>
		<key>FakeID</key>
		<dict>
			<key>ATI</key>
			<string>0x0</string>
			<key>IntelGFX</key>
			<string>0x0</string>
			<key>LAN</key>
			<string>0x0</string>
			<key>NVidia</key>
			<string>0x0</string>
			<key>SATA</key>
			<string>0x0</string>
			<key>WIFI</key>
			<string>0x0</string>
			<key>XHCI</key>
			<string>0x0</string>
			<key>IMEI</key>
			<string>0x0</string>
		</dict>
		<key>Inject</key>
		<false/>
		<key>USB</key>
		<dict>
			<key>AddClockID</key>
			<true/>
			<key>FixOwnership</key>
			<true/>
			<key>Inject</key>
			<true/>
		</dict>
	</dict>
