No sound and CMOS issues

[-Tex-]

I install and boot Yosemite finally but have two serious issues:

1. I can't get sound work at all.I tried to to install voodoohda but without success, sound devices appears in system report but sound doesn't work. I tried to fix it by adding device id into config.plist but i didn't find hdef device in IOService. I'm using clover so i tried to apply FixHDA, hide device appears in IOService, I put it id into config.plist but, after reboot voodoohda device disabled at all.

2. Mac writes something into CMOS after reset or shutdown that made dimm2 slot for ram on my motherboard not working . If i have ram stick in that slot i have memory errors and app crashes in windows, memtest86 even doesn't start test of ram stick in that slot. It's present until i reset CMOS. I try to apply etc fixes in Clover and replace AppleRTC.kext with patched one, CMOS doesn't reset but bug with dimm2 slot still present.

My kernel bootflags are: -v dart=0 npci=0x2000 kext-dev-mode=1

 

My specs are:

CPU: AMD Phenom II X4 810

MB: Gigabyte GA-MA790FXT-UD5P (sound codec: realtek alc889a)

GPU: ASUS HD7850-DC2-2GD5-V2

RAM: 8 Gb (4x2Gb)

hi, 

 

the Codec ALC889a  work with the native AppleHDA.kext, you only need add HDEF Layout_id 12 or 0C to your DSDT , or try inject in clover layout_id

 

    "layout-id", 

                            Buffer (0x04)

                            {

                                 0x0C, 0x00, 0x00, 0x00

                            }, 

 

 

HDEF PCI0.txt

[-Tex-]

one man in kernel testing thread wrote that npci=0x2000 flag makes applehda not working

[Yayiin]

not know, I have set it to my Clover config    <string>slide=0 dart=0 darkwake=0 npci=0x2000 kext-dev-mode=1</string>

 

and no problem, mine 889a working native , ofc with HDEF in the DSDT.aml

Concerning VoodooHDA: Do you have your speakers hooked to the back or the front? If so try switching them. Also, check under the VoodooHDA prefpane to see if you need to change any values to get sound to work. If that fails, if you have a 6 port audio, hook your audio to your black port.

I did not notice that default out was Headphones (green-front) in syspref-sound, changed it to line-out (green-rear) and sound began to work. Will have to try to start sound with applehda, but now main problem is CMOS issue that i wrote above.

try this kext to see if solve the problem CMOS :  RTC_legacy.zip

[-Tex-]

I have already installed patched AppleRTC. Do I need use RTC_legacy in pare with patched AppleRTC or i have to return back original AppleRTC or maybe delete AppleRTC at all ?

[Yayiin]

1. backup your AppleRTC.kext, then delete from S/LE

2. Install the LegacyRTC with Kext Wizard app

3.  open Kext Wizard, Repairpermissions/Rebuild caches/reboot

[-Tex-]

I can't boot with RTC_legacy stuck on USBF:

I found patch that disables all cmos writes from AppleRTC for mac os x 10.9

This works for me on 10.9 Mavericks:

perl -pi -e 's|\x41\x89\xd7\x41\x89\xf4|\xe9\xb8\x00\x00\x00\x90|;' /System/Library/Extensions/AppleRTC.kext/Contents/MacOS/AppleRTC

 

Verify your source file before patching: 

md5 AppleRTC 

MD5 (AppleRTC) = 4b1d28ac48a2a7b35ed6b2034e0fd912

 

This patch completely disables all CMOS writes from AppleRTC

Look for analogue for yosemite

Solved problem with CMOS. I have to use ElliottForceLegacyRTC.kext in pare with original AppleRTC.kext. Mo more problems with RAM after reset or shutdown. I found new issue: ethernet link not always up on start, led on ethernet card not blink until i replug cable. I use onboard Realtek RTL8111 ethernet card with kext 1.2.3 from this thread. Sometimes when link is up on startup i can see in kernel start log line that says something about "Realtek RTL8111 1Gbit link is up on en0". 

[Yayiin]

try this one and look if work better, backup your and install this one with Kext Wizard app/rebuild caches/repairpermissions/reboot

 

 

 

RTL8111.zip

 RTL8111.zip seems works fine. I decided to make work sound through AppleHDA. I try to add device from HDEF PCI0.txt into DSDT but get unfixable error during aml compilation: Object does not exist (DTGP)

Hello!

 

You have to add method (DTGP) to your DSDT. There should be a patch for it.

 

Have fun.

[-Tex-]

I applied DTGP patch to my dsdt

# Add method DTGP to the main block, it's used by other patches#
into method label DTGP remove_entry;
into definitionblock code_regex . insert
begin
Method (DTGP, 5, NotSerialized)\n
{\n
    If (LEqual (Arg0, Buffer (0x10)\n
            {\n
                /* 0000 */    0xC6, 0xB7, 0xB5, 0xA0, 0x18, 0x13, 0x1C, 0x44, \n
                /* 0008 */    0xB0, 0xC9, 0xFE, 0x69, 0x5E, 0xAF, 0x94, 0x9B\n
            }))\n
    {\n
        If (LEqual (Arg1, One))\n
        {\n
            If (LEqual (Arg2, Zero))\n
            {\n
                Store (Buffer (One)\n
                    {\n
                        0x03\n
                    }, Arg4)\n
                Return (One)\n
            }\n
            If (LEqual (Arg2, One))\n
            {\n
                Return (One)\n
            }\n
        }\n
    }\n
    Store (Buffer (One)\n
        {\n
            0x00\n
        }, Arg4)\n
    Return (Zero)\n
}
end

then applied patch that adds HDEF device

into device name_adr 0x001B0000 parent_label PCI0 remove_entry;into device label PCI0 insert
begin
Device (HDEF)\n
{\n
    Name (_ADR, 0x001B0000)\n
    Method (_DSM, 4, NotSerialized)\n
    {\n
        Store (Package (0x04)\n
            {\n
                "layout-id", \n
                Buffer (0x04)\n
                {\n
                    0x0C, 0x00, 0x00, 0x00\n
                }, \n
                "PinConfigurations", \n
                Buffer (Zero) {}\n
            }, Local0)\n
        DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))\n
        Return (Local0)\n
    }\n
}
end

compiled and save dsdt then place it in root directory, reboot and get no result: no sound, no any sound device in system report. Here is my dsdt
