As in the subject, how do I get sound to work in 10.6.5?

According Tkinkwiki.org you have the same sound card as a T61.
Many people seems to manage to have sound with there T61, so you may expect some good results :

10.6.2 : http://www.insanelymac.com/forum/index. ... pic=188569

10.6.3 : http://www.insanelymac.com/forum/lofive ... 17783.html

And here a very useful link from a member of this forum ! : http://forum.thinkpads.com/viewtopic.ph ... 96#p612096

Thanks for the reply, in the last linked thread 'Grandflash' says -

"In my DSDT (X61tablet) i fixed a lot of devices like IntelHDA1984 (Sound), IntelGMAx3100(Video), Serialport for Tablet and WiFi of course. I had a legacy kext in E/E doing this prior. If your interested:
http://osx86.co/f57/installing-snow-leo ... 50669.html
He provided a patched AppleHDA.kext too (X61tablet with AD1984) in the linked post above."

I tried the kexts in the link he provided, AppleHDA.kext.zip and that did not work. Then I went to another link for 10.6.3, and it mentions kexts but none were there. Then I went to your 10.6.2 link and downloaded T61_6465_SNOW_Leopard.zip. In that zip file were the sound kexts that "iloveant" used. One was an AppleHDA.kext along with an AppleAzaliaAudio.kext. He said "Reload the AppleHDA.kext and and AppleAzaliaAudio.kext and sound will be back as in 10.6.1 with injected strings in com.apple.Boot.plist. I did that, and while I now have a sound mixer and HDA sound device, I still have no sound. I am using kext helper for all of this and clearing text cache etc. I will keep trying. When he says "with injected strings in com.apple.Boot.plist." that is a mile above my head. Am I supposed to be doing something with a plist?

Grandflash's kext goes with a DSDT edit ... you have to update your DSDT to make it work !

If you don't know how to do so, you can read "DSDT edit for dummies" made by Silencer.

Useful applications are DSDTse (to extract your DSDT, but it is a buggy text editor ..), Fraise (good text editor) and iaslme (to compile to .aml and to de compile in .dsl which is text)

I think the DSDT edit you have to do is to replace "Device(HDEF)" with this one but I am not sure ...

Code: Select all

Device (HDEF)
            {
                Name (_ADR, 0x001B0000)
                Name (_S3D, 0x03)
                Name (RID, Zero)
                Name (_PRW, Package (0x02)
                {
                    0x0D, 
                    0x04
                })
                Method (_PSW, 1, NotSerialized)
                {
                    Noop
                }

                Method (_DSM, 4, NotSerialized)
                {
                    Store (Package (0x08)
                        {
                            "layout-id", 
                            Buffer (0x04)
                            {
                                0x0A, 0x00, 0x00, 0x00
                            }, 

                            "subsystem-id", 
                            Buffer (0x04)
                            {
                                0xA0, 0x00, 0x00, 0x00
                            }, 

                            "subsystem-vendor-id", 
                            Buffer (0x04)
                            {
                                0x6B, 0x10, 0x00, 0x00
                            }, 

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

Thanks for the tip. Using DSDTse, it looks like the current DSDT entry for Device HDEF is 970 lines in length. So, I am replacing those 970 lines with these couple of dozen? Is the section to be replaced starting from the line with HDEF up until the next 'Device' section starts?

Edit: Finally got sound working using the AzaliaTurboTP1984.kext from the below link. There is another AppleHDA.kext there I will try tomorrow to get audio line out working.

Here's what's working on this build, and what is not. Any suggestions appreciated;

Working;
Sound
QE
Speedstep (I think, based on temperatures)
Airport WiFi
Battery Guage
Sleep
USB
Thinklight
Apple Keyboard, all keys (except brightness)
External USB Mouse
Advanced Minidock
VGA Output on dock

Not Working;
DVI Output on dock
Bluetooth
Brightness

I installed the AppleHDA.kext and modified the EFI per the instructions by priitv8 in the below thread. I now have full working sound, including SPDIF output through the Advanced Mini Dock. Still looking for pointers on the non-working items above.

I have attempted to follow your procedure listed, as well as retrace your footsteps here. Yet I cannot obtain the same results on my R61e. Which DSDT were you using ?
