Optimized AppleHDA for Realtek ALC 887/888b on Lion [OLD]

Re: Optimized AppleHDA for Realtek ALC 887/888b on Lion

I'm struggling with editing the DSDT for HDEF, not sure what to edit, what I have in my original DSDT is:

If I paste any of the edit over the lines of code in my original I get a black screen, if I try to include both it won't compile, tried slotting the relevant bits in-between but it still won't compile, just getting loads of errors.

Is there a dsdt for your motherboard in the dsdt database? If not, reply with your dsdt attached.

Hi, the only DSDT in the database is for Rev1.0 Mobo, I have Rev2.0 with FA bios.

Here is the DSDT.dsl I have extracted from my machine, corrected to compile using DSDTSE

Thanks

You have to add Method DTGP to the dsdt
Do not replace the existing HDEF.
Insert the following code after Name and before OperationRegion (line 7159)

                Method (_DSM, 4, NotSerialized)
                {
                    Store (Package (0x04)
                        {
                            "layout-id", 
                            Buffer (0x04)
                            {
                                0x77, 0x03, 0x00, 0x00  
                            }, 

                            "PinConfigurations", 
                            Buffer (Zero) {}
                        }, Local0)
                    DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
                    Return (Local0)
                }

The fix for the warning message is replace MUT0, 0x0FFF with MUT0, 0xFFFF.

I'm so stuck. I think I did all the required steps. I just got the "early recommendation" GA-Z77-DS3H board. All is working working great except for the 887 sound.

Can you check out my files? I seem to meet the requirements you posted in post 1.

Could it be this bit? I kept this method in the HDEF part of the DSDT as removing it gave "undefined errors" elsewhere when compiling.

Field (HDAR, WordAcc, NoLock, Preserve)
            {
                DCKA,   1, 
                        Offset (0x01), 
                DCKM,   1, 
                    ,   6, 
                DCKS,   1, 
                        Offset (0x08), 
                    ,   15, 
                PMES,   1
            }

Thank you!!

Can't open the zip files, verify zips and attach. The dsdt/HDEF edit is correct. Need to see the IOReg to see what is wrong.

dsdt Edit Tips/DSDTSE
1. Search _T_0
Replace T_0
2. Search _T_1
Replace T_1
3. Search MUT0, 0x0FFF
Replace MUT0, 0xFFFF

P8h67M-LX don't work.

IOReg is corrupt. IORegistryExplorer/File/Save a Copy A ...., open copy to verify, attach. dsdt looks correct.

Both attachments are corrupt. Try DSDTSE/Registry Info/Get.

I do it! I download ioregexp. from http://www.osx86.net/view/93-ioregistryexplorer.html
