ALC889a on Gigabyte GA-P35-DS3R Input Microphone Working - Snow Leopard

[lithiumion]

Hi

 

This is my fixed DSDT.aml + AppleHDA & HDAEnabler Kexts to get your GA-P35-DS3R's ALC889a fully working.

 

It took me a while to figure out where I was going wrong. I used to generate and edit my dsdt.dsl and recompile it, but I never added the right code to fix the mic nor did I replace the AppleHDA.kext with the correct one after that.

 

The correct code I found in the "How to Patch DSDT" folder thats included in "SL_Pack_v4.zip"

                               0x85, 0x08, 0xEC, 0x10    
                           },

                           {
                               "Realtek ALC889A"     
                           }, 

                           "PinConfigurations", 
                           Buffer (0x28)
                           {
                               /* 0000 */    0x10, 0x90, 0xA1, 0x01, 0x20, 0x90, 0xA1, 0x02, 
                               /* 0008 */    0x80, 0x30, 0x81, 0x01, 0x90, 0x40, 0x21, 0x02, 
                               /* 0010 */    0x30, 0x40, 0x11, 0x01, 0x40, 0x40, 0x01, 0x01, 
                               /* 0018 */    0x50, 0x60, 0x01, 0x01, 0x60, 0x20, 0x01, 0x01,

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

 

I used to get 14 compilation errors every time I tried to recompile my dsdt.dsl. That was due to an extra "}" in the "How to patch DSDT with LAN and HDEF functions.pdf" file. It's a typo but I finally figured it out.

 

Check the attached picture to see where it is.

 

I have nVidia 9400GT/1GB, you will need to decompile and edit the DSDT.aml file to suite your card.

To edit yout card's VRAM total size edit the part where it says:

 

 "VRAM,totalsize",
                               Buffer (0x04)
                               {
                                   0x00, 0x00, 0x00, 0x40
                               },

 

For a card with 128MB of VRAM use 0x10, for 512MB of VRAM use 0x20 etc. For a 512MB card it should look like this:

 

 "VRAM,totalsize",
                               Buffer (0x04)
                               {
                                   0x00, 0x00, 0x00, 0x20
                               },

 

 

Use DSDTSE to edit the file instead of TextEdit so you wont get compilation errors.

 

 

PS: I force the system to boot into 32Bit Kernel by editing com.apple.Boot.plist to look like this:

 

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Kernel</key>
<string>mach_kernel</string>
<key>Kernel Flags</key>
<string>arch=i386 -x32</string>
</dict>
</plist>

 

 

All thanks goes to the guys who did the hard work, THe KiNG, Taruga, stickpin, Kabyl, karaakeha1, MadTux, tmongkol and the rest. Thank You

anyone have any luck getting the sound working under the 64bit kernel? Is it even possible?
